Allow creation of event with start and end in different timezones
If I try to put in a flight which starts and ends in different timezones with evolution, I can't separately select the timezone for the start and end of the event: if I change the timezone after putting in the start time, it doesn't adjust the displayed time (I agree that this is right in some situations, but wrong in the case of a flight). Of course I can do the addition or subtraction, but this can be tricky if the start and end locations have different Daylight Saving Time rules: anyway it's the sort of thing that computers are supposed to do for us. I did try to build evolution and submit a patch, but it requires a whole chain of tools requiring other tools to be installed which aren't available on my distro (openSUSE-Leap-15.0). My evolution version is 3.26.6-lp188.8.131.52 from the OpenSUSE repo.
