The addon only supplies start time and end time. There is no notion of duration for an epg entry.

Do you calculate duration?

Yes, for list items on guide and other PVR screens. Also for video player for the OSD. Example of 1Hr show:-

php:
<value condition="String.StartsWith(ListItem.Duration,01:00">1h00m</value>

 
I had problems quite a few months back where the duration on the recording screen which had been working fine, suddenly stopped working using this method. At the time I was told it was a backend issue and nothing got done. Then without reason, months later something must have been changed, because is started displaying the duration correctly again. The incorrect duration I'm seeing currently on the guide screen is a carbon copy of the previous error with recording durations.

Have just checked my current recordings and timers. All are showing correct durations and use the exact same variable.
