Syncing Time Zone via IPMI

▤ Summary

In addition to “normal” shenanigans time zones bring, I got another interesting one – my IPMI servers required me to manually tell them whether daylight saving is in effect or not. As all my servers were Supermicro (M11SDV-4CT-LN4F and A1SRi-2558F) I decided to use Supermicro’s powerful IPMI to programmatically deal with that issue. As long as I keep script on my main server that will update time zone information (if needed) twice a day (at 02:00 and 03:00), it should be enough to keep me happy. As retrieving time zone information via IPMI is not something that’s standardized, I contacted Supermicro’s support to get the details. Using the same principle, it’s easy enough to update IPMI: Trying to script this change is a bit tricky.
