I believe the issue might not be related to the setenv function, but rather
with tzset(). As you can see here[1], when we set TZ before we call the
unit-testing binaries, the tests which were failing (EST5 ones that I
separated with t-datetest) pass on 'win test (0)', and the ones which
were passing (UTC ones, t-date) fail. (Although some tests on linux are also
failing, but that can be explained by the fact that t-date runs first
and sets the TZ to UTC, afterwhich t-datetest runs and fails, although
this is not conclusive). Therefore, I am almost certain that the issue
is with changing the timezone during runtime on windows and not with setting
TZ variable with setenv(). CC'ing Johannes to see if he has any insights
on this.

Other that that, there are many places in this patch where indentation
is done with spaces instead of tabs, so it'd be good to change that.

Thanks.
