Re-Sampling Overrun's between time slots
Click this check box in the Time-Dependent Distributions Time-Slot dialog if the
value being sampled represents a time and if you want times sampled in the previous
cell not to overlap into the current cell.
The default is OFF (not checked). Only use this facility if you are sure you need it
because it can distort the results collected from your simulation if used when not
required.
Example:
In this example of arrivals to a hospital's "accident and emergency" unit the time
interval between arrivals is very different at different times of day. Rush hour is a
very busy time.

(Should Re-sample Overruns)
Without Re-Sampling Overruns set on the 17:30 - 18:30 period a sample taken at time
17:29 could easily result in the arrivals jumping right over the 17:30 - 18:30 period.
This is because if an arrival occurred at 17:29 (in the first time slot in the above table)
the time to next arrival might be sampled as 69 minutes from 17:29 - and no arrivals
would occur in the busy time.
