Subject: [PATCH] Use standard -t option for touch.

```
Non-GNU touch do not have the -d option to take free form
date strings.  The POSIX -t option should be more widespread.
For this to work, date needs to output YYYYMMDDHHMM.SS date strings.

Hi,

Simon, please don't use "undisclosed recipients". After all, this is 
_open_ source, and you make it really inconvenient to reply.

I just checked on an SGI machine, and it has "-t". In related news, it 
also has /usr/bin/printf.

Ciao,

Hhmmmmm.

This still does not seem to fix the breakage I am seeing on
OpenBSD.

But thanks anyway for trying.
