Steps to reproduce:

1. Setup a machine with ~60s time difference with Zabbix server.
2. Use Zabbix Linux template which checks system time difference

Result:
It causes flapping trigger execution on borderline cases. See screenshot (I had the {$SYSTEM.FUZZYTIME.MAX} set as 30s

Expected:
Only one warning/problem entry until issue is fixed.

I suggest that a new variable {$SYSTEM.FUZZYTIME.MIN} is introduced which defaults to half of {$SYSTEM.FUZZYTIME.MAX}. Can macros have math?  maybe by default

{$SYSTEM.FUZZYTIME.MIN} = {$SYSTEM.FUZZYTIME.MAX} / 2 ?

or

{$SYSTEM.FUZZYTIME.MIN} = 30s (which is half of default 60s value)

Any suggestions are welcome?
