I have Redmine on my local Linux box where the timezone is Central Time (Canada).
My time zone in Redmine is set appropriately (UTC -600) and all times were logged correctly until last Sunday when the Daylight Savings switched. Now all times are off by 1 hour.

That tells me that Redmine did not realize the change in CST to CDT.

To get around this, I changed my timezone (in Redmine) to be UTC -500 but that is not my preferred solution.
I think switching to TZInfo (found here: would be a simple solution to the problem.

As you said, installing TZInfo should solve this problem since Rails' builtin TimeZone doesn't handle DST.

ruby script/plugin install tzinfo_timezone

Can you confirm ?

I did not do a thorough test but appears to be working correctly now.
