Is result milliseconds since epoch?

[James McMahon <js...@gmail.com>]

I have a string representation of a datetime parsed from a lengthy
filename, attribute myValue with value of 20221003055959. If I convert to a
true datetime value and then apply toNumber() to that, does toNumber()
return milliseconds since the epoch? The expression language guide doesn’t
go into too much detail.
Thank you.

Yepp I would say it comes with milliseconds, but if you need it you can convert afterwards to seconds like in my example “${myDate:toDate("yyyy-MM-dd HH:mm:ss","UTC"):toNumber():divide(1000)}”
