[Orgmode] Table formula referencing cells with HH:MM time strings, incorrect result

[Jeff Kowalczyk]

I am trying to use HH:MM time strings from clocktables in a table formula. First
time I've used table formulas, BTW.

When fetching the cells as remote(), I got strange results. The behavior is the
same for regular references, so here's a regular-reference test case:

| 17:36 | 17:36 |
| 19:45 | 19:45 |
| 24:53 | 24:53 |
| 40:57 | 40:57 |
| 43:02 |  43:2 |
| 45:14 | 45:14 |
| 46:09 |  46:9 |
| 48:56 |   6:7 |
| 49:28 |   7:4 |
| 55:18 | 55:18 |
| 80:10 |     8 |
| 88:14 |  44:7 |
#+TBLFM: $2=$1

The objective is to multiply time (decimal) by a constant, so if anyone has a
tip for parsing HH:MM using a function instead of reinventing, thanks in 
advance.

Thanks,
Jeff
