Re: difference between an integer and current-dateTime

Hi all,
 B  B  I've got a number 1585039138 for example (which is number of
seconds since epoch 1970-01-01T00:00:00Z UTC). I wish to find the
duration (in minutes or seconds) between previous number and
current-dateTime(). I wish to do this with XSLT (2/3 both are fine with
me, preferably non schema aware). I expect this difference to be always
positive, since the number will change depending on what moment (at any
moment, I wish to find this difference) it is calculated. How can I do

You can compute the difference between two dates or dateTimes with the
substraction operator:

xs:dateTime('1970-01-01T00:00:00Z') + xs:dayTimeDuration('PT' ||
1585039138 || 'S')

current-dateTime() - (xs:dateTime('1970-01-01T00:00:00Z') +
xs:dayTimeDuration('PT' || 1585039138 || 'S'))

will give you the difference as a dayTimeDuration between the current
dateTime and the number.

(current-dateTime() - (xs:dateTime('1970-01-01T00:00:00Z') +
xs:dayTimeDuration('PT' || 1585039138 || 'S'))) div
xs:dayTimeDuration('PT1S')

I used the XPath 3 || string concat operator in some places but the
XPath 2 concat function would work as well, the whole date/dateTime and
duration arithmetics is an essential part since XSLT/XPath 2 anyway.
