I've tried to smartadd European summertime for 2013 (March 31st) in both Chrome on my desktop and in the Android app. Both failed.
Summertime ^2013-03-31 at 02:00 #datetime
Smartadding this from www sets the time to 01:00am. Adding this in the Android app makes it crash (or rather: smartadding it without the time, *then* trying to set at time to 02:00, makes it crash). Setting the time to 01:59 goes well.
This issue was reported both 3 and 4 years ago and is still troublesome.
