due date actually set = mod(due date specified, 24 hrs)

I just tried setting a task as "due in 24 hrs", and found it set as "right now". Likewise I tried setting it as "due in 48 hrs 15 min" and got "due in 15 min", etc.
I'm not sure if this can be called a bug; anyway it'd surely be convenient if 24+hrs manner of due date specification were allowed (in addition to using "tomorrow" or whatever alike).
