Our team is in Shanghai. I made some change and comments in Flow JIRA at 10 o'clock and I can see my previous action from the history tab of Flow JIRA. They were modified indeed at 10 o'clock. But from my colleagues' computer, it showed to me that I made the modification at 3 o'clock. I don't know why. Hope somebody of you can help me to figure out what is the root cause of this problem. Many thanks !
