Weird clock

When I play the clock sometimes runs down to 0.0 and stays that way for a while. I even managed to take a screenshot.

What is the purpose of this?

I assume it can sometimes happen when connection is slow and local and server clock get desynchronized (at least that’s how I imagine it works :smiley: ), so I assume the clock should always be correct on the server, just not cought up, on local browser, but I will try asking someone more clever.
