Recurring TODO with hours not scheduled correctly

[Justin Vallon]

Newbie org-mode user.  Wondering about some odd recurrence behavior.

emacs --no-init-file

# test.org

* TODO shovel snow

M-x org-schedule RET RET

* TODO shovel show
  SCHEDULED: <2019-12-03 Tue>

Add time:

* TODO shovel show
  SCHEDULED: <2019-12-03 Tue 09:00 .+1h>

Complete: C-c C-t

* TODO shovel show
  SCHEDULED: <2019-12-03 Tue 10:00 .+1h>
  :PROPERTIES:
  :LAST_REPEAT: [2019-12-03 Tue 00:52]
  :END:
  - State "DONE"       from "TODO"       [2019-12-03 Tue 00:52]

Again: complete: C-c C-t

* TODO shovel show
  SCHEDULED: <2019-12-03 Tue 11:00 .+1h>
  :PROPERTIES:
  :LAST_REPEAT: [2019-12-03 Tue 00:57]
  :END:
  - State "DONE"       from "TODO"       [2019-12-03 Tue 00:57]
  - State "DONE"       from "TODO"       [2019-12-03 Tue 00:52]

My understanding of .+TERM is that the new scheduled time should be now
+ term.  However, from this instance and testing with other terms, it
seems to be "current date + scheduled-time" + HOURS.  Completing again
advances the time by one hour, leaving the date as today.

For ".+2d", the new scheduled date/time is 2d away (at the same time),
and re-completing does not change the new schedule time.

(equal org-version "9.1.9")
