minutes at

minutes at evaluates a sample as the number of minutes in the day after midnight. The sample must be in the form hh:mm, in 24 hour time.

A typical use of this function would be to determine the time between when a specimen was collected and when it was processed. For example, given the following case fragment:

ABC                       7.3    5.6    6.1
ABC_Collection_Time       13:02  09:46  14:17
ABC_Process_Time          17:45  12:39  20:43

minutes at ABC_Process_Time – minutes at ABC_Collection_Time > 360
