I'm a bit confused about the date format - when I search from the Topsy
"advanced search" web interface and specify a date and time range, e.g.
September 22 from 6pm-7pm, the time boxes say "PST" next to them, but the
results that get returned appear to be from 6-7pm EST, my own time zone.
Then, if I look at the mintime and maxtime values in the URL, they
are mintime=1316728800&maxtime=1316732400 which convert to Thu, 22 Sep 2011
22:00:00 GMT and Thu, 22 Sep 2011 23:00:00 GMT respectively, which are 5pm
and 6pm EST, not 6pm and 7pm EST as the search result tweets are actually
from. This would make sense if I was searching for recent tweets since
Daylight Savings started, but not for searching for tweets from back in
September. How does this work / is this documented anywhere?
