You are reminded 5 minutes and 1 minute before the actual
time, at the time, and every minute thereafter.
When you log off,

printed the next message.

The time of day is in the form
.Ar hhmm
where
.Ar hh
is a time in
hours (on a 12 or 24 hour clock), and
.Ar mm
are minutes.
All times are converted to a 12 hour clock, and assumed to
be in the next 12 hours.
.It Cm \&+
If the time is preceded by
.Ql Cm \&+ ,
the alarm will go off in hours and minutes
from the current time.
.El
.Pp
If no argument is given,
.Nm leave
prompts with "When do you
have to leave?". A reply of newline causes
.Nm leave
to exit,
otherwise the reply is assumed to be a time.
This form is suitable for inclusion in a
.Pa .login
or
.Pa .profile.
.Pp
Leave ignores interrupts, quits, and terminates.
To get rid of it you should either log off or use
.Ql kill \-9
giving its process id.
