Changeset 72140 in vbox for trunk/src/VBox/Runtime/r3/win

Timestamp:

Message:

IPRT/time: misc fixes (incorrect offUTC conversion sign, forgotten storing of offUTC, incorrect month/day calculation for first day of month, avoiding assertions when leap year needs to be recalulated) for local time, make RTTimeImplode process local time correctly, plus an implementation of RTTimeLocalNormalize and RTTimeConvertToZulu. Much improved testcase exercising overflow handling in the local time case.
