Timer Events - Cron Expression

[MaheshkumarSundaram]

Hi @ralphhanna,

Just wanted to clarify a quick thing about cron expression.

Field	Required	Allowed values	Allowed special characters
Seconds	False	0-59	* , -
Minutes	True	0-59	* , -
Hours	True	0-23	* , -
Day of month	True	1-31	* , -
Month	True	1-12	* , -
Day of week	True	0-6	* , -

I suppose the above would be the classic format supported in the Timer Definitions. Time is always in reference to UTC I suppose.
Correct me if I am wrong?

Does it also support the values JAN–DEC and SUN-SAT for Month & Day of Week? Also, are the special characters L, W, ? & # supported?

@MaheshkumarSundaram - if you've cracked the CRONs with this package, could you please share me the knowledge that you've obtained ? I've not explored much on the Timer Events. It'd be great if could share your knowledge.

Thank You

Sorry, I didn't look into this in detail as the existing support for Duration & Timer Cycles were sufficient for my usecases.

Hi @MaheshkumarSundaram

Sorry for taking so long to answer, I had to search it though.

The answer is yes, but I would recommend using the ISO 8601 format 'R3/PT25S' -- repeat 3 times 25 seconds delay
