Each of those times are different, the +0000 would indicate a zonal difference. They are 1:27 AM, 7:15 PM and 8:06 PM Greenwich Mean Time
Meaning that the device used has a time stamp set to GMT. Either the user is posting from a location in the GMT area (London) or is using GMT so that their general location cannot be determined.
Each “time zone” is approximately 1000 miles across (E->W) at the equator and ~12,000 miles long. Applying known percentages, only about 1/3 of each time zone is land.
YMMV, depending on latitiude
