It would be nice to use the same.
I'm not sure I understand you correctly but strftime can do this:
OGR_DATETIME_FORMAT = "%Y-%m-%dT%H:%M:%S"
gives for example 2016-01-10T08:25:12 and
OGR_DATETIME_FORMAT = "%Y-%W-%dT%H:%M:%S"
gives 2016-01-10T08:25:12 for the same time - 10.1.2016 is on week two
(strftime: %W = Week number with the first Monday as the first day of
week one (00-53))
Sorry, it was me who misunderstood your question/suggestion. I thought
that printing with the above format was not possible yet and that's why I
pointed to what GMT does. But if GDAL can do it already, than sorry for
the noise.

I think that there needs to be separate options for date and datetime,
i.e., OGR_DATE_FORMAT and OGR_DATETIME_FORMAT.

Folks,
The OGRFeature::GetFieldAsString returns date/time fields formatted in
non-standard way. For example date is output as "year/month/day" as
more usual "year-month-day". This causes problems in many programs.
I suggest adding a new config option OGR_DATE_FORMAT, which, if set,
would make the method return date/time formatted according to it. I
suggest that we use the strftime and its format argument as the target
for the new option.
The implementation is complicated a bit when milliseconds and
timezones are involved since they are not included in the struct tm
used by strftime. I suggest that we assume seconds are formatted as
:\d\d in the format and simply add milliseconds (as .\d\d\d) and
timezone (as [+-]\d\d(:\d\d)), if they exists, after the second.
Do you think this needs a RFC?
I'm willing to implement the changes.
Ari
