I like to use the 12 hour time display option to set and present times. In most cases it is simply more easily understood.
On a number of occasions it's been important to carefully schedule the timing of a mailing, for example to coincide with the lifting on an embargo on a press release issued by a third party. These can commonly be embargoed until 00:01 on a given date. Id like to set the timing for a mailing to go out at 00:01, but as far as I can tell the field won't accept '00' as the hour value. What time should I set in this field to represent 1 minute past midnight?
