It depends on the timezone information available on the system and on
the system's local time zone. If the system's local time zone is UTC,
that will be used. Otherwise, the time will use an unnamed timezone
at offset +0000. That winds up with the difference that you see. See
the docs for time.Parse:
When parsing a time with a zone offset like -0700, if the offset
corresponds to a time zone used by the current location (Local), then
Parse uses that location and zone in the returned time. Otherwise it
records the time as being in a fabricated location with time fixed at
the given zone offset.
