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.
