When adding an event with following alarm spec. in iRony:
```
BEGIN:VALARM
ACTION:DISPLAY
TRIGGER;VALUE=DURATION:PT0S
DESCRIPTION:Default Mozilla Description
END:VALARM
```
it is then converted to:
```
BEGIN:VALARM
ACTION:DISPLAY
TRIGGER;VALUE=DATE-TIME:19700101T000000Z
END:VALARM
```
Which means that alarm description is lost and the trigger is wrong.
Another story is if such alarms are handled/displayed correctly by other clients e.g. Roundcube. I'm afraid they might be handled as no-alarm.
