Dave, Jonathan, Niko,

The GPS week number rolled over today at 16:59:42 localtime.  We monitored the system as the rollover happened.  There were no errors observed.

Items that we checked (from T1990166):

• System time on a workstation (zotws5) - watching the ntp
• System time on h1dc0 - watching the ntp
• /proc/gps on h1dc0 - watching the timing system
• /proc/gps on a front end (h1lsc0) - watching the timing system
• The counters on the SYS_CUST_TIMING_TRIMBLE_GPS screen and the associated M12 screen.
• The GPS clock in the control room.

After the rollover the gps time read good on the frontends, dc0, the wall clock and the system times look good on the workstations.  We will need to check the ntp settings on dc0, it appears to be off.  That will be a Tuesday task.

The trimble showed a 2048 week counter, which showed it handling the 2nd rollover in GPS just fine.
