To help, we need to know a few things ...
What OS do you have GAD installed on?
What GAMFT version are you on?
Also, what version of Java are you running?
What timezone are you located in?
The release note you mention below is for GAD version 4.0, not MFT. There was an issue with the roll to Daylight Savings time corrected back on that version. This has not been an issue since that was corrected.
