Can date and time-stamping be altered by changing the user's preferences?

Date and time-stamping are essential components of GLP compliance to ensure that the file was actually created on the specified date. To avoid the possibility of individual’s altering their computer time-clock, the System Administrator should configure the settings of each user computer and then prevent users from gaining access to this facility.

 

When signing a LabChart data file, the client computer sends the current time to the GLP Server to check for synchronization. If there is a discrepancy of greater than 60 seconds between the client and server computer clocks, the signing process fails.
