I am utilizing the scheduled tasks feature of ColdFusion (CF 8) so robustly, that we have had to dedicate multiple servers that do nothing but run scheduled tasks all day long. When Daylight Savings Time hits we always end up running into issues with tasks running early or late because CF8 decides to change the scheduled run time.
For instance, one task runs Daily at 23:20, and on Friday night after the task executed, instead of scheduling the next run for 23:20 EST on Saturday, it scheduled the task for 00:20 EDT on Sunday.
At what point does CF (or the JVM) change the time and why isn't it at 02:00 on the Sunday of the change?
What can I do to avoid this in the future, besides putting my servers into a state which doesn't observe DST?
We're using the JVM that came with CF 8 (1.6.0_04).
Any help is appriciated. Thank you.
