Hence it runs on local time too. There's no problem with that. But Linux is not Windows. Even though logrotate runs on local time, the system is aware of UTC time. For comparing two events, this should be done with UTC time. One part of the bug is that logrotate rotates the log files instead of not changing anything if it incorrectly guesses that a file has been written in the future. So, if the timezone changes several times (e.g. during a travel), some logs may be lost, even recent ones, while they would normally be kept e.g. for several weeks! Logs are important data.
