System clocks on slave and master being out of sync can result in erroneous reporting of "seconds behind master" on slave servers, with the lag increasing further as the clocks drift further apart.
This problem can be avoided by keeping server clocks synced with a network time source. On Linux systems, this could be accomplished by properly configuring and running the NTP service.
Eliminate erroneous reporting of replication lag on the slave due to unsynced system clocks.
