Indeed! Thanks for replying. I tried this on my side and it seems to be working stillusing the formula in a Prepare recipe.
The idea is to rebuild the date with hours:minutes:secondes, from the time difference in seconds.
"00"[0,2-(floor(diff(date1, date2, "seconds")/3600)).length()] + (floor(diff(date1, date2, "seconds")/3600))
+ ':'
+ "00"[0,2- (floor(mod(diff(date1, date2, "seconds"), 3600)/60)).length()] + (floor(mod(diff(date1, date2, "seconds"), 3600)/60))
+ ':'
+ "00"[0,2- (mod(mod(diff(date1, date2, "seconds"), 3600),60)).length()] + (mod(mod(diff(date1, date2, "seconds"), 3600),60))
You can obviously use a Python recipe instead of the formula to rebuild this field too.
I hope this helps.
Have a nice day,
Pauline
