Achilles’ heel of TM1: Daylight savings time (DST)

Once again it’s the time of the year (March 31st) when we shift into summer time (or daylight savings time (DST)). That’s great: days are getting longer and you start feeling that the summer really is near. The bad thing is if you happen to have a TM1 production environment somewhere and you have scheduled chores to execute at specific point of time. The thing is: TM1 is unable to handle daylight savings time correctly. It still amazes me how this is possible? In other words how they haven’t made any fixes to correct this? Maybe it’s just so deep deep deep inside the legacy business logic or something. Anyhow, the point is you’re on your own and have to deal with this issue yourself.

So, after Easter Monday remember to go through the chore schedules in your TM1 environment and reschedule them to start up at correct time.
