Summary
This page is to explain what happens to the Date Time field values when entering and/or exiting DST in JIRA.
Solution
Example
Assume Sydney is entering DST on October 4th 2015 02:00. At this time, Australia/Sydney time will shift forward an hour, becoming October 4th 2015 03:00.
The created date value for issue ABC-678 is 1/Oct/15 9:42 PM, and will remain as is.
A new issue ABC-679 created after 4/Oct/15 3:00 AM will use the current (DST) time for its created date.
Answers
The existing values in Date Time field and Date/Time history will remain unchanged.
The Date Time field and Date/Time history for events scheduled after Daylight Savings Time begins will reflect the new updated timezone.
