qmail-date-localtime.patch

Dr.Daniel J. Bernstein's software

This patch causes the various qmail programs to generate date stamps in
the local timezone. I find GMT too annoying to convert from/to. I make
no warranties that it will work in your timezone, however it works for me.

Works with qmail 1.01 to 1.03.

To apply this patch, cd into the qmail source directory and type...
