[Ulf Jasper]

branch: master
commit 74e9799bd89484b8d15bdd6597c68fc00d07e7f7
Author: Ulf Jasper <address@hidden>
Commit: Ulf Jasper <address@hidden>

    Handle missing start-time when importing ical event (Bug#33277)
    
    * lisp/calendar/icalendar.el (icalendar--convert-ical-to-diary): Set
    start time only if it is explicitly given in ical.  Do not use
    start-time as default for end-time (Bug#33277).
    
    * test/lisp/calendar/icalendar-tests.el (icalendar-import-bug-33277):
    New.  Test fix for Bug#33277.
