Redmine

There are 3 area which shows "Activity".

1. Activity in "Project"
2. Activity in "User Profile" (offical name maybe different ...), which shows User Name, Mail(optional), projects to which the user joins in the left, recent activity of the user in the right.
3. Activity History of the user, which shows activity history in 30 days period (days are set differently at the installation). You could go to the past history and come back.

We observed the following.

1. Among these 3 "Activity", Date/Time is different in 2. from 1 and 3.
2. Compared with the actual modification date and time, 2. shows wrong date/time, while 1. and 3. shows correct date/time.
3. Wrong Date/Time is related to Time zone setting of User profile of the viewer, which means who is to view Activities. It is not the setting of the user to be viewed.
   • For example, if Time zone is set to JST, ie. GMT+09:00(Tokyo), activities between 00:00-08:59 (in JST) are diaplayed as it was in the day before.
     • example: Activity at Dec.22, 2016 06:35 AM => Dec. 21 , 2016 06:35 AM
   • In order to confirm, if Time zone is changed to GMT, ie. GMT+00:00(London), all activities are displayed correctly.

We wonder if these 3 activity listing use different calculation logic.

Please note:

1. There are several open issues about Time zone, such as #6991, #5425, #5091. I am not sure if the issue described here is the duplicate of existing ones. If so, I am happy if someone would point it out.
   • I made this issue to clarify the phenomena. hope this helps.
2. The issue happens but, in my opinion, the severity is minor.

• Redmine version 3.1.1.stable
