Do the terms "GMT offset" and "UTC offset" refer to the same "offset"?

I.e. if I have a Python/Django timezone-aware datetime called mydt, and I print it this way:

In [1]: mydt.strftime('%Y-%m-%dT%H:%M:%S%z')
Out[1]: '2013-07-20T23:50:00+0200'

Is the UTC offset returned for %z in the form +HHMM or -HHMM the same as a GMT offset for the same date? In my case it is +0200.

I tried googling, but what I've found is the history of GMT and why UTC was needed later on. Although things look like GMT and UTC are the same, I need to be 100% sure.

  • From developer point of view they are the same although geographer would probably argue they aren't. – zero323 Sep 09 '13 at 20:57

UTC = GMT +/- 0.9s, so they are almost the same
