You may wish to consider using the ISO date/time format - - - - - your
example would look like 20160805T0850 .
I have adopted such as, for me at least, I no longer need to worry about
whether its month first or day first (its biggest values to smallest ones)
and the time is also a 24 hour clock and seconds and parts thereof can
also be added . For a higher volume sales center this would enable very
precise logging of sales where the time of sale could possibly even be
used as an identifier for said sale.
