Andrew's solution will work just fine provided your time values are always less than 24 hours, and provided you always subtract the smaller time from the greater. If you do it the other way around, e.g. 00:00:02 - 00:00:03 the answer will be PT23H59M59S (if I remember correctly).

Also note that 1:15.28 is not a valid xs:time value; you need to expand it to 00:01:15.28.

Dear list,

I have a need for calculating differences in times. The times are from sporting events and are in these formats:
Here it means one minute, 15 seconds and 28 hundreds of a second (or 69 hundreds of a second) so the difference here is 41 hundreds of a second (0.48 as it would say in my output)

The format could also be:
where the time means one hour, 11 minutes, 15 seconds and 28 (or 69) hundreds of a second. The difference her should then be one minute and 41 hundreds of a second (1:00.41)

Up until now I have done this in an external function in a program (windows service (daemon)) that is doing all conversions for us. Problem is that a new structure of the service has stopped the external functions from working. I will not go back to the old structure because the new structure made the service faster.

I am using Saxon for transformations, and I have been in contact with Mr. Michael Kay regarding problems with external functions (thanks for all the help!, but we have not found a solution. (dll with external functions has been put in the GAC even without luck)

A complete solution is not necessary (although it would be nice), but some pointers towards which direction I should go - how to solve this - would help me a lot.
Here you go:


Turn your values into xs:times, then substract one from the other to
get a xs:dayTimeDuration, then format or use the various extractor
