Leap year and Daylight Savings Time bugs are *not* Garden Variety for Microsoft: they're a Microsoft specialty. Until Windows XP, you couldn't really count on your Windows box handling the Spring Forward, or the Fall Back. The OOXML "standard" for Excel has enshrined a leap year bug:

Windows: a special case, wrapped in an exception, bundled inside of a custom hack job.

My favourite is still the Microsoft 32-bit clock/timer bug, which meant that Win '9x (and others?) simply could not run any longer than 47.9 days. I understand this made trouble for the occasional air traffic control center.

But the main reason I like it so much is there used to be so many Windows fanbois on ZDNet and similar sights, who swore up and down that they had uptime stats running over three months, over 6 months, sometimes even (with solid admin skills, careful set-up, selective application choices and judicious control over patching) eight, nine or ten months...

Of course, these claims were entirely bogus.

PS: Technically, Linux had a somewhat similar bug, that meant Linux systems would never report an uptime over 497 days (the Linux kernel clock ticked at 100 Htz, rather than 1000 Htz) -- but this bug didn't crash the system or harm its smooth operation, so the system could actually run longer, it just didn't report a higher number when queried for its uptime.

The universal reaction I encountered when that bug was announced was "How did anyone ever keep their system up that long, anyway?" :)
