According to Daniel 9:25-26 the total construction time for the Second Temple was 49 Years which includes interruptions in building; the First Temple took 7 Years to build: in both cases once construction was completed there's no more construction time to account for.
So it's clear you didn't pay attention to the context...maybe I should stop playing stump the chump
Why not address what I actually offered and the scriptures cited therein? Here they are and more.
1 Kings 6:38 KJV
38 And in the eleventh year, in the month Bul, which is the eighth month, was the house finished throughout all the parts thereof, and according to all the fashion of it.
So was he seven years in building it.
Ezra 3:8-13 KJV
8
Now in the second year of their coming unto the house of God at Jerusalem,
in the second month,
began Zerubbabel the son of Shealtiel, and Jeshua the son of Jozadak, and the remnant of their brethren the priests and the Levites, and all they that were come out of the captivity unto Jerusalem; and appointed the Levites, from twenty years old and upward, to set forward the work of the house of the LORD.
9 Then stood Jeshua with his sons and his brethren, Kadmiel and his sons, the sons of Judah, together, to set forward the workmen in the house of God: the sons of Henadad, with their sons and their brethren the Levites.
10
And when the builders laid the foundation of the temple of the LORD, they set the priests in their apparel with trumpets, and the Levites the sons of Asaph with cymbals, to praise the LORD, after the ordinance of David king of Israel.
11 And they sang together by course in praising and giving thanks unto the LORD; because he is good, for his mercy endureth for ever toward Israel. And all the people shouted with a great shout, when they praised the LORD,
because the foundation of the house of the LORD was laid.
12
But many of the priests and Levites and chief of the fathers, who were ancient men, that had seen the first house, when the foundation of this house was laid before their eyes, wept with a loud voice; and many shouted aloud for joy:
13 So that the people could not discern the noise of the shout of joy from the noise of the weeping of the people: for the people shouted with a loud shout,
and the noise was heard afar off.
Ezra 4:1-24 KJV
1
Now when the adversaries of Judah and Benjamin heard that the children of the captivity builded the temple unto the LORD God of Israel;
2 Then they came to Zerubbabel, and to the chief of the fathers, and said unto them, Let us build with you: for we seek your God, as ye do; and we do sacrifice unto him since the days of Esarhaddon king of Assur, which brought us up hither.
3 But Zerubbabel, and Jeshua, and the rest of the chief of the fathers of Israel, said unto them, Ye have nothing to do with us to build an house unto our God; but we ourselves together will build unto the LORD God of Israel, as king Cyrus the king of Persia hath commanded us.
4 Then the people of the land weakened the hands of the people of Judah, and troubled them in building,
5
And hired counsellors against them, to frustrate their purpose,
all the days of Cyrus king of Persia,
even until the reign of Darius king of Persia.
6
And in the reign of Ahasuerus, in the beginning of his reign, wrote they unto him an accusation against the inhabitants of Judah and Jerusalem.
7
And in the days of Artaxerxes wrote Bishlam, Mithredath, Tabeel, and the rest of their companions, unto Artaxerxes king of Persia; and the writing of the letter was written in the Syrian tongue, and interpreted in the Syrian tongue.
8 Rehum the chancellor and Shimshai the scribe wrote a letter against Jerusalem to Artaxerxes the king in this sort:
9 Then wrote Rehum the chancellor, and Shimshai the scribe, and the rest of their companions; the Dinaites, the Apharsathchites, the Tarpelites, the Apharsites, the Archevites, the Babylonians, the Susanchites, the Dehavites, and the Elamites,
10 And the rest of the nations whom the great and noble Asnappar brought over, and set in the cities of Samaria, and the rest that are on this side the river, and at such a time.
11 This is the copy of the letter that they sent unto him, even unto Artaxerxes the king; Thy servants the men on this side the river, and at such a time.
12 Be it known unto the king, that the Jews which came up from thee to us are come unto Jerusalem, building the rebellious and the bad city, and have set up the walls thereof, and joined the foundations.
13 Be it known now unto the king, that, if this city be builded, and the walls set up again, then will they not pay toll, tribute, and custom, and so thou shalt endamage the revenue of the kings.
14 Now because we have maintenance from the king's palace, and it was not meet for us to see the king's dishonour, therefore have we sent and certified the king;
15 That search may be made in the book of the records of thy fathers: so shalt thou find in the book of the records, and know that this city is a rebellious city, and hurtful unto kings and provinces, and that they have moved sedition within the same of old time: for which cause was this city destroyed.
16 We certify the king that, if this city be builded again, and the walls thereof set up, by this means thou shalt have no portion on this side the river.
17 Then sent the king an answer unto Rehum the chancellor, and to Shimshai the scribe, and to the rest of their companions that dwell in Samaria, and unto the rest beyond the river, Peace, and at such a time.
18 The letter which ye sent unto us hath been plainly read before me.
19 And I commanded, and search hath been made, and it is found that this city of old time hath made insurrection against kings, and that rebellion and sedition have been made therein.
20 There have been mighty kings also over Jerusalem, which have ruled over all countries beyond the river; and toll, tribute, and custom, was paid unto them.
21 Give ye now commandment to cause these men to cease, and that this city be not builded, until another commandment shall be given from me.
22 Take heed now that ye fail not to do this: why should damage grow to the hurt of the kings?
23 Now when the copy of king Artaxerxes' letter was read before Rehum, and Shimshai the scribe, and their companions, they went up in haste to Jerusalem unto the Jews, and made them to cease by force and power.
24
Then ceased the work of the house of God which is at Jerusalem.
So it ceased unto the second year of the reign of Darius king of Persia.
Zechariah 1:12-16 KJV
12 Then the angel of the LORD answered and said, O LORD of hosts,
how long wilt thou not have mercy on Jerusalem and on the cities of Judah,
against which thou hast had indignation these threescore and ten years?
13 And the LORD answered the angel that talked with me with good words and comfortable words.
14 So the angel that communed with me said unto me, Cry thou, saying, Thus saith the LORD of hosts; I am jealous for Jerusalem and for Zion with a great jealousy.
15 And I am very sore displeased with the heathen that are at ease: for I was but a little displeased, and they helped forward the affliction.
16
Therefore thus saith the LORD; I am returned to Jerusalem with mercies: my house shall be built in it, saith the LORD of hosts, and a line shall be stretched forth upon Jerusalem.
Haggai 1:1-15 KJV
1
In the second year of Darius the king, in the sixth month, in the first day of the month, came the word of the LORD by Haggai the prophet unto Zerubbabel the son of Shealtiel, governor of Judah, and to Joshua the son of Josedech, the high priest, saying,
2 Thus speaketh the LORD of hosts, saying,
This people say, The time is not come, the time that the LORD'S house should be built.
3 Then came the word of the LORD by Haggai the prophet, saying,
4
Is it time for you, O ye, to dwell in your cieled houses, and this house lie waste?
5 Now therefore thus saith the LORD of hosts; Consider your ways.
6 Ye have sown much, and bring in little; ye eat, but ye have not enough; ye drink, but ye are not filled with drink; ye clothe you, but there is none warm; and he that earneth wages earneth wages to put it into a bag with holes.
7 Thus saith the LORD of hosts; Consider your ways.
8
Go up to the mountain, and bring wood, and build the house; and I will take pleasure in it, and I will be glorified, saith the LORD.
9 Ye looked for much, and, lo, it came to little; and when ye brought it home, I did blow upon it. Why? saith the LORD of hosts. Because of mine house that is waste, and ye run every man unto his own house.
10 Therefore the heaven over you is stayed from dew, and the earth is stayed from her fruit.
11 And I called for a drought upon the land, and upon the mountains, and upon the corn, and upon the new wine, and upon the oil, and upon that which the ground bringeth forth, and upon men, and upon cattle, and upon all the labour of the hands.
12 Then Zerubbabel the son of Shealtiel, and Joshua the son of Josedech, the high priest, with all the remnant of the people, obeyed the voice of the LORD their God, and the words of Haggai the prophet, as the LORD their God had sent him, and the people did fear before the LORD.
13 Then spake Haggai the LORD'S messenger in the LORD'S message unto the people, saying, I am with you, saith the LORD.
14
And the LORD stirred up the spirit of Zerubbabel the son of Shealtiel, governor of Judah, and the spirit of Joshua the son of Josedech, the high priest, and the spirit of all the remnant of the people; and they came and did work in the house of the LORD of hosts, their God,
15 In the four and twentieth day of the sixth month,
in the second year of Darius the king.
Ezra 6:14-15 KJV
14 And the elders of the Jews builded,
and they prospered through the prophesying of Haggai the prophet and Zechariah the son of Iddo. And they builded, and finished it, according to the commandment of the God of Israel,
and according to the commandment of Cyrus,
and Darius,
and Artaxerxes king of Persia.
15 And this house was finished on the third day of the month Adar,
which was in the sixth year of the reign of Darius the king.
Solomon was seven (7) years in building the temple according to 1 Kings 6:38.
There are four (4) years from the second year of Darius to the sixth year of Darius. Solomon was thus eleven (11) years in building the temple when the second temple was completed in Ezra 6:15.
There are thirty-five years from 19BC to 17AD. Solomon was thus forty-six years in building the temple at the time of John 2:20 because it was counted as completed circa 16-17AD.
Did this help? or is it rather that you choose not to believe that the people in those days believed the temple of Solomon to be forever as the scripture says?
