I understand that the time a comment was added is part of its text and cannot be easily converted into a different timezone or format. Correct formatting has to be done before a comment is added to the repo, be it automatically or by calling some functions in the script (we just need to know which ones).<br>
Speaking of duplicates, 5c1490e26b only describes one thing, the comment timestamps. This ticket suggests that the entire UTC/local conversion is somehow broken. A developer has to take a look to say whether a single common defect or two unrelated ones are causing the effects.<br>
If you are concerned about the number of open tickets, you can close any of the two and I will copy the info into the other ticket (not that it would make any sense with so many tickets left open already).
