bb date

[Chey]

The -D switch does what it's supposed to there is no doubt about that.
But the GNU date command doesn't like that switch at all.

I was hoping it would be possible to add another date format that the
BB's date command would accept as a valid date for setting the date
with 'date -s'. Possibly one of the following:

2006-09-08 08:09:10 - fairly standard format also accepted by GNU date
(ISO 8601 i think)
Fri, 08 Sep 2006 08:11:25 -0400 - RFC 2822 date format accepted by GNU
date as well
09/08/2006 08:13:12 - another format accepted by GNU date

The first one is probably the best bet and fairly easy to implement. I
don't see this as a bug but a feature request and will not press it.
If others think it's a good idea then great maybe someone can
implement it. If not...like i said i won't press it :) I know most
people are busy doing other things.

Thanks all,
Chey
