You're right. Using UTC doesn't solve any DST bug, despite what I initially thought. I think we just need to remove the whole set of changes about UTC in `parse-time-string'. We also need to adapt tests in test-org-clock since the same time difference could have different meanings depending on the time zone. I can do that later, if no one objects. WDYT?n Refactoring time functions in Org is still useful, though. Regards, -- Nicolas Goaziou
