They told us on the Friday before Labor Day, that if we were at a business that was closed "for the holiday", but we were there between 12 and 1 or after 5, that we shouldn't record it during those times, but enter it after 1 or before 5. That was an addendum to the instructions to record them as cloH. One of the advantages to using cloH is that you only have to use the non-delivery buttons for cloH on one package and the diad extends it to all. Whereas with clo1, you have to go through and enter that for each package. In the case of a manufacturing facility, for example, one might have 100 packages, and the place was closed for a holiday that UPS doesn't honor, or a day that the customer chooses to close for business reasons, then the driver would have to use about an additional 297 keystrokes to complete the stop.
