One A.M. forever…

Well it's that time of year. Microsoft’s Windows 95 had a bug in the time shift from DST to standard time. In the Spring on the correct date at 1:00 a.m., it changed the time to 2 a.m. In the fall on the correct date at 2:00 a.m., it changed the time to 1:00 a.m. Then at 2:00 a.m. it changed the time to 1:00. Then at 2:00 a.m. it changed the time to 1:00.Then at 2:00 …

I can imagine the QA test for that feature of the operating system. The test was NOT this: Set the date to the last Saturday in October. Wait 24 hours and see if the time was changed correctly.. QA people have a lot to do and they’re in a hurry. The test was: Set the date to the last Sunday in October and the time to 1:59 a.m. Wait two minutes and note whether the time has been set back to 1 A.M. Restore the correct date/time and go on to the next test.
