I recently saw this in wordbuilders general chat:
Basically, a message posted and stared more than 9 hours ago shows up as posted 8 hours ago in the sidebar. I suspect it is an issue about the list do not update that often. However, it persisted in refresh for up to now when I post this (20 min after), indicating that those times can be wrong for at least 1/3 of the time.
The delay between updates seems way too long, especially compared to the delay of only a few seconds to respond to staring events. Does it really take that much capacity to update the chat sidebar times more often than >20 minutes?
