date-time-hourf

Arguments: date-time

Returns the value in the hourf (fractional hour) slot of date-time, which must be a date-time object. The value is nil if the slot is not set. Otherwise it is a non-negative rational less than 1. This value cannot be changed with setf and this function.

(require :datetime)
(use-package :util.date-time)

;; date-time is 1985/04/12 10:15:30, that is 15 and a half
;; minutes after 10 AM April 12, 1985.
(setq a (date-time "1985-04-12T10:15:30"))
(date-time-hourf a) -> 31/120  ;; = 15.5 minutes

See date-time.htm for information on support in Allegro CL for parsing and generating time expressions using the ISO 8601 standard.
