I didn't run into any Y2K problems - for UNIX/Linux itself this was mostly a non-issue due to times being stored in at least 32-bit time_t at that point. Individual applications may have had their own Y2K related issues of course, but I didn't run into any. However, one issue I did run into nearly two years later was when UNIX time_t rolled over to 1 billion seconds. The company I worked with at the time was running WU-IMAP for their email server, plus additional patches for qmail-style maildir support. We came into work on September 10th 2001 and all the email on our IMAP server was sorted in the wrong order. Turns out there was a bug in the date sorting function in this particular maildir patch (see http://www.davideous.com/imap-maildir/ http://www.davideous.com/imap-maildir/ - "10-digit unix date rollover problem"). I think we were the first to report it to the maintainer due to the timezone we were in. First time for me in identifying and submitting a patch to fix a critical issue in a piece of open source software! My co-worker and I were chuffed. Of course, we swiftly forgot about it the next day when planes crashed into the NY World Trade Center.
