I believe the same as most Unix systems.  If I recall correctly, the strings
in the TZ setting (e.g., "EST") never really have any material impact on the
time, but exist only for presentation.  It's the numeric offset embedded in
the value that is key.  So you should fine it works with "TZ=EST5" or
"TZ=EST5EDT" (the most appropriate for Eastern).

At least on my system, without any setting Cygwin is also using my local NT
setting.  So if your machine itself has the proper local time you can
probably drop TZ altogether.  But if you set it to anything (e.g., your
"EST") then it is obeyed, and in the case of "EST" there is no offset, so
it's equivalent to "EST0" which is UTC time-wise.
