Is there any way in XQuery to get the current time in milliseconds since some Epoch?

Question

XQuery offers various date/time functions like current-dateTime(), however I can\'t seem to find one which gives me the time in mi

Answer 1

thank you for the tips. I modify the code for Oracle Service Bus 11g (OSB 11g) Xpath editor in case someone else needs it

{ (fn:current-dateTime() - xs:dateTime("1970-01-01T00:00:00-00:00")) div xdt:dayTimeDuration("PT0.001S") }

Answer 2

Additional tricks on Aditya's answer for OSB 11g.

There has an annoying bug on XQ Editors that will change div and operator into a , (comma).

Just put a conversion function in front of that code. such as xs:long, xs:string

ex.

{ xs:long((fn:current-dateTime() - xs:dateTime("1970-01-01T00:00:00-00:00")) div xdt:dayTimeDuration("PT0.001S")) }

Answer 3

(current-dateTime() - xs:dateTime("1970-01-01T00:00:00-00:00")) div xs:dayTimeDuration('PT0.001S')

returns the number of seconds as a duration, and then divides by 1 millisecond to get the number of milliseconds as a number.
