Cumbersome to edit time [regression]

Created by: CendioOssman

It seems the 2.x code lost the separate input widgets for start and end time. This makes it rather annoying to modify time as the previous interface had quick suggestions for common intervals.

It looks like this was removed in 697a03e5. But I don't see any rationale. Did someone consider the feature pointless? Or was it removed because no one had ported the supporting code?

Would a PR be accepted returning the old behaviour?
