Document that clock drift will cause lock system to fail

Created on 25 May 2010, over 14 years ago
Updated 1 December 2023, about 1 year ago

The timeout values used in the lock system rely on the local system time with the resulting timestamp being written to the semaphore table to be shared amongst processors in a web farm. Clock drift of more than 30 milliseconds (the default value for expiry in the system) between systems will render it useless in a web farm environment since locks will not be honoured and the behaviour will be unpredictable.
