Upon event of Daylight Saving time changes we had seen that the jobs triggering incorrectly. As a work around we had changed the job schedule timings manually. Do advice the steps to be taken to avoid this issue further.

We have found the below point in release notes, however not sure the actions to be taken to avoid the issue.
Fixed an issue where some scheduled jobs were firing at incorrect times during/after Daylight Savings Time changes.

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.
