Running 8.4.6 hosted on Linux, if I do this...
SELECT to_char('2011-03-01 12:00' AT TIME ZONE 'GMT0BST', 'HH24:MI TZ');
to_char
---------
12:00
(1 row)..I don't get a timezone- I can live with that. If I do this...SELECT to_char(('2011-03-01 12:00' AT TIME ZONE 'GMT0BST')::TIMESTAMP WITH TIME ZONE, 'HH24:MI TZ');
to_char ----------- 12:00 GMT (1 row) ..then I get the GMT time with a timezone 'GMT'- that's what I want. But if I do this...SELECT to_char(('2011-04-01 12:00' AT TIME ZONE 'GMT0BST')::TIMESTAMP WITH TIME ZONE, 'HH24:MI TZ');
to_char ----------- 13:00 GMT (1 row)..then I get the time corrected for daylight saving- which is what I want- but the timezone doesn't indicate that daylight saving has been applied.
In the general case, how can I get TZ indicating whether daylight saving is in effect? Alternatively, is there a flag I can retrieve indicating that a timestamp has been corrected for DST so that I can select an alternative name for display?
