System time is out of sync flapping

[yurtesen]

In OS Linux monitoring, there is a trigger which checks the remote system time.However when the time slowly drifts, it starts flapping many times. This is quite annoying.
Please add {$SYSTEM.FUZZYTIME.MIN} and create a recovery expression for hysteresis.

The bug report due to flapping of this trigger is closed without an understanding of the problem.. I added a comment about it and no response yet.

This is an issue I can confirm, full comment below with fix, template needs to be updated to
({TRIGGER.VALUE}=0 and fuzzytime(/Linux generic/system.localtime,{$SYSTEM.FUZZYTIME.MAX})=0 ) or ({TRIGGER.VALUE}=1 and fuzzytime(/Linux generic/system.localtime,{$SYSTEM.FUZZYTIME.MIN})=0)

This is an issue I can confirm, we had this Flap 25 times in a single evening.

I added the {$SYSTEM.FUZZYTIME.MIN} and set it to 30

Here is the modification to the trigger I made
I changed
fuzzytime(/Linux generic/system.localtime,{$SYSTEM.FUZZYTIME.MAX})=0

to
({TRIGGER.VALUE}=0 and fuzzytime(/Linux generic/system.localtime,{$SYSTEM.FUZZYTIME.MAX})=0 ) or ({TRIGGER.VALUE}=1 and fuzzytime(/Linux generic/system.localtime,{$SYSTEM.FUZZYTIME.MIN})=0)

in the Linux generic Template

for the Trigger System time is out of sync (diff with Zabbix server > {$SYSTEM.FUZZYTIME.MAX}s)

Hi gelowe
Can you also comment on the now closed issue ticket? It is sad that the person who replied to the ticket did not quite understand the problem and abruptly closed it.
