Whenever you change the system clock time you will affect timers used by EMS. If the clock time is moved forward then you may have many timers go off at once, as for example heartbeat and activation times. You may notice the “slow clock tick xxx” and messages were expired are unexpectedly issue.
If the time is set back then you may have timers delayed. You may also have heartbeats delayed, activations on other systems due to lack of heartbeats.
If a system clock is regularly jumping in time it should be addressed. On some systems, where system clocks are drifting a little higher than usual, more frequent system time syncs have reduced the jumps on a system time. By reducing the time jumps to smaller than the heartbeat time you can avoid most false activations.
