Here's what I'm working with:

appt time |time in | variance from appt. time | time out |variance from
appt. time

I am trying to show the variance from appointment time and actual time in,
and the variance from the appointment time and the time out. (clear as mud?)
I'd like to show it in positive or negative time. In other words, show a
distinction between time in that was EARLIER from the appt. time and LATER
than the appt. time.

Can anyone help?
