REvelation 1:8 I am the Alpha and the Omega, the Beginning and the End,[c] says the Lord,[d] who is and who was and who is to come, the Almighty.
so Here God is claiming to be the beginning and the end, which would be implied that HE was outside of time.
here is a clip from a site that may help:
God lives outside the bounds of time as we know it (Isaiah 57:15). Our destiny was planned before the beginning of time (2 Timothy 1:9; Titus 1:2) and before the creation of the world (Ephesians 1:4; 1 Peter 1:20). By faith we understand that the universe was formed at Gods command, so that what is seen was not made out of what was visible (Hebrews 11:3). In other words, the physical universe we see, hear, feel and experience was created not from existing matter, but from a source independent of the physical dimensions we can perceive.
God is spirit (John 4:24), and, correspondingly, God is timeless rather than being eternally in time or being beyond time. Time was simply created by God as a limited part of His creation for accommodating the workings of His purpose in His disposable universe (see 2 Peter 3:10-12).
