Time Tolerance

The file server (or servers) and the vovserver may be unsynchronized. If that occurs, comparing the timestamp of a file with the start time of a job, may produce an incorrect result due to the clock offset.

While it is easy to synchronize the clocks, it may be occasionally necessary to run VOV on a network that is slightly offset.

Tolerance can be set to accept timestamp comparisons with a tolerance of a few seconds. A typical value for the tolerance is less than 10 seconds. By default, no tolerance is allowed; it is assumed that the network is synchronized.

Setting the Tolerance

Time tolerance is set by adding a line in the policy.tcl file. Example:

set config(timeTolerance) 2

The tolerance can also be set via the browser interface. To do so, log in as ADMIN and visit the Admin page.
