 The origin of this problem is presently unknown but the FS time can get seriously out of step. To fix this, **while not recording** start the ''​fmset''​ program from an ''​oper@pcfshb''​ terminal and issue the "​+"​ and "​-"​ commands, then quit from fmset (ESC). Restart fmset and the FS time should now be correct. You may need to resync the mark5B pps after this procedure. ​ The origin of this problem is presently unknown but the FS time can get seriously out of step.

 +Be sure to check that FHG=off. ​ Sometimes if there is a power glitch while the Mark5 is still recording, it can get '​stuck'​ in record mode.  This will need to be stopped with disk_record=off,​ then run fmset again.
