Hi all,
  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 that?
