Hi rebOldes,
This is my version, but as Volker has shown it is made redundant by
Difference in the latest REBOLs except the latest non-experimental, non-beta
View (1.2.1):
subtract-datetimes: function [
"Subract one date from another returning time between them."
a [date!]
b [date!]
] [delta-days delta-hhmmss a-hhmmss b-hhmmss] [
delta-days: subtract a/date b/date
a-hhmmss: either a/time [a/time] [00:00:00]
b-hhmmss: either b/time [b/time] [00:00:00]
return add (multiply 24:00:00 delta-days) (subtract a-hhmmss b-hhmmss)
]
Regards,
Brett
