Hm, Borland's localtime manages to return NULL under certain
circumstances (e.g. wintime.test, test 1.2). Nobody tests for this,
since 'localtime' isn't supposed to do this, possibly leading to
crashes.
Patch: We only call this function if we are at least one day into
the epoch, else we handle it ourselves (like we do for times < 0).
