The Lunar module touched down at 20:17 UTC on July 20 Neil Armstrong made his descent to the moons surface at 02:56 UTC on July 21. UTC is close enough to GMT give or take 0.9 seconds.
Not counting Daylight Saving Time (a.k.a. Summer Time), there are 39 different time offsets used around the world: UTC-11, UTC-10, UTC-9:30, UTC-9, UTC-8, UTC-7, UTC-6, UTC-5, UTC-4:30, UTC-4, UTC-3:30, UTC-3, UTC-2, UTC-1, UTC, UTC+1, UTC+2, UTC+3, UTC+3:30, UTC+4, UTC+4:30, UTC+5, UTC+5:30, UTC+5:45, UTC+6, UTC+6:30, UTC+7, UTC+8, UTC+8:45, UTC+9, UTC+9:30, UTC+10, UTC+10:30, UTC+11, UTC+11:30, UTC+12, UTC+12:45, UTC+13 and UTC+14.

The U. S. time zones are UTC-11, UTC-10, UTC-9, UTC-8, UTC-7, UTC-6, UTC-5, UTC-4 and UTC+10. The African time zones are UTC, UTC+1, UTC+2 and UTC+3.
Russia has many time zones (UTC+3, UTC+4, UTC+6, UTC+7, UTC+8, UTC+9, UTC+10, UTC+11, UTC+12); China has only one (UTC+8).
The Australian mainland is divided among four different times during Standard Time (UTC+8, UTC+8:45, UTC+9:30 & UTC+10) and six different times during Summer Time (UTC+8, UTC+8:45, UTC+9:30, UTC+10, UTC+10:30 & UTC+11). Including all of Australia's island territories and its Antarctic station, the total number of Australia's time offsets is eight during Standard Time (UTC+6:30, UTC+7, UTC+8, UTC+8:45, UTC+9:30, UTC+10, UTC+10:30 & UTC+11:30) and nine during Summer Time (UTC+6:30, UTC+7, UTC+8, UTC+8:45, UTC+9:30, UTC+10, UTC+10:30, UTC+11 & UTC+11:30).

There are 40 time zones, consisting of the following: UTC-12, UTC-11, UTC-10, UTC-9:30, UTC-9, UTC-8, UTC-7, UTC-6, UTC-5, UTC-4:30, UTC-4, UTC-3:30, UTC-3, UTC-2, UTC-1, UTC, UTC+1, UTC+2, UTC+3, UTC+3:30, UTC+4, UTC+4:30, UTC+5, UTC+5:30, UTC+5:45, UTC+6, UTC+6:30, UTC+7, UTC+8, UTC+8:45, UTC+9, UTC+9:30, UTC+10, UTC+10:30, UTC+11, UTC+11:30, UTC+12, UTC+12:45, UTC+13, UTC+14
Apollo 11 was launched on July 16, 1969 at 13:32 UTC. Its lunar module landed on July 20 at 20:17 UTC. Armstrong actually stepped down onto the surface of the Moon on July 21 at 02:56 UTC. So it took 4 or 5 days, depending on how you count.
