Created attachment 366761 [details] Screenshot indicating the issue Timestamp shown in ews-app's status-bubble hover-over message is in future. For example in the attached screenshot, the status-bubble is for currently in-progress build. It shows a timestamp of "April 05 2019 01:28:13 GMT -0400 (EDT)". This seems to be 8 hours ahead of the actual time.
This seems to be due to incorrect timezone (UTC) in ews-app's settings.py

Ideally, we would be showing the correct time to everyone, which can only be done in client side JavaScript.

I finally got to the bottom of this issue. We are sending incorrect timestamp from buildbot. We are converting the timestamp to local time (pst) while generating epoch timestamp. While generating status-bubble (in django app) we interpret the timestamp as UTC time, which makes the timestamp in future. Previous patch was just a workaround. Updated patch fixes the root-cause. Tested on uat instance.
