A Hebrew Wikipedia user wrote to me that after he posted he saw a human timestamp that says "in a minute" - in the future. I haven't seem it myself yet, but it does sound like something that could come from moment.js. Future timestamps are definitely wrong :)

OK, I reproduced it: This happens if the machine's local time is earlier than the server time. Not all computer clocks are in sync. It would be nice to have all visible timestamps be synchronized with server time.
