server: Use the monotonic time counter also on the server side.
This seems to address the server side time discrepancy, though I would still encourage thorough auditing because mouse axes shouldn't invert even if there is a large discrepancy in timer origination points (both timers still kept accurate times). There is likely still an underflow somewhere.
