Sets the maximum allowable discrepancy between filer time and server time. If there is a large discrepancy, it probably means that enough is wrong somewhere that the filer time should not be synchronized with the server time, no time synchronization takes place, and a message to that effect is sent to the console. The value is an integer followed by one of the following letters:
s - for seconds
m - for minutes
h - for hours
The default is 30m, which specifies 30 minutes.
