Logical expression to start action

[georgyiii]

Hi! I want to start action based on time difference between test previous status change and current status change time. For example i need to set snmp value if time difference last status change and current status time is less than 30 minutes. I try to use expression: ('%SimpleStatus%'=='DOWN') and ('%StatusChangedTime%'-'%PreviousStatusTime%'<00:30:00)
But it didn't work
What i do wrong? How i can trigger action based on time difference?

%StatusChangedTime% and %PreviousStatusTime% variables return string/text values.
They can be compared, but cannot be calculated (added, subtracted ,etc)
As I understand you correctly, you need to use expression like the following:
('%SimpleStatus%'=='DOWN') and ('%CurrentStatusDuration%' < '00:30:00')
or
('%SimpleStatus%'=='DOWN') and (%CurrentStatusDuration_sec% < 1800)

Could you make some examples to explain what you need?
E.g.
10:00:00 TestItem01 Status: Ok
10:20:00 TestItem01 Status: Bad <Start Action/Alert>
10:40:00 TestItem01 Status: Bad <No Action should be triggered>

11:00:00 TestItem01 Status: Ok
11:35:00 TestItem01 Status: Bad <No Action should be triggered>
11:55:00 TestItem01 Status: Bad <No Action should be triggered>

Is this correct example?

In such case expression should look like the following:
('%SimpleStatus%'=='DOWN') and (%PreviousStatusDuration_Sec%+%CurrentStatusDuration_sec% < 1800)
