Description

The normal find command can only specify time arguments in terms of whole days. The MacOS find(1) man page reports the use of unit suffixes to give greater control over the time range, such as "1h" or "1d4h":

             If units are specified, this primary evaluates to true if the
             difference between the file last access time and the time find
             was started is n units.  Possible time units are as follows:

             s       second
             m       minute (60 seconds)
             h       hour (60 minutes)
             d       day (24 hours)
             w       week (7 days)
             y       year (365 days)
