bb date

[Chey]

BB's date command seems to only accept two formats for setting the
date. Are these to formats subject to bb's date command only or should
those two formats work on other distros as well?

I'm asking because I cannot set the date with bb's date command and
use that same command to set the date on my Debian box.

I'm having trouble creating a portable script to set the date because of this.

Any thoughts on that?

I'm using bb 1.2.1.

Thanks,
Chey
