Even more smelly is the precision of “5:31 AM.” I am not sure hour:minute was a clear and universal concept in 1357. At the time, “canonical hours” were used (https://en.m.wikipedia.org/wiki/Canonical_hours https://en.m.wikipedia.org/wiki/Canonical_hours ); they corresponded to night watches and bell tolling times, and certainly weren’t notated like “5:31.”
