Because it shouldn't. An EXDATE with VALUE=DATE does indeed exclude the whole 
day, but an exrule by definition has the same VALUE type as DTSTART and thus 
takes the hour and minute from DTSTART if required.

This means: recur every minute.

> EXRULE:FREQ=DAILY;BYDAY=MO,TU

This means: exclude all events every monday and tuesday at 12:00 UTC, as the 
time is taken from DTSTART. Contrary to what you might think, this EXRULE 
still defines date/time values, not date-only values! 

Just like 
RRULE: FREQ=DAILY:BYDAY=MO,TU 
doesn't mean the whole day, but only at 12:00 UTC. RRULE and EXRULE are of the 
same type RECUR and thus can't behave differently.

Cheers,
Reinhold
