# TimeDiff.fun

# This function can be used to calculate the delta

#  time in milliseconds between two times.  The times

#  (Time1, Time2) are obtained using the 'GetTime()'

#  built-in Phantom function.

# This function works for time differences up to an hour

#  but can be modified for times greater than an hour
