To answer the other answer above - GMT doesn't have daylight savings as such as it must remain as a constant time to measure all others against, but many countries in that time zone do have a daylight savings system.
So for example currently in the UK we're not on GMT, we're on BST (British Summer Time) which and then when the clocks go forward in the Autumn we switch back to GMT.
So in the winter 7pm ET is midnight GMT, but during the summer 7pm ET is still midnight in London BST, but it's actually 11pm GMT. Hope that makes sense!

If you are referring to Eastern Time, USA, then GMT is 5 hours ahead, so that would be Midnight
Yep, add 5 hours for EST and 4 for EDT because I don't think GMT has daylight savings... but I could be wrong.
