qmail/qmail-date-localtime.patch

   1 This patch causes the various qmail programs to generate date stamps in
   2 the local timezone. I find GMT too annoying to convert from/to. I make
   3 no warranties that it will work in your timezone, however it works for me.
   4
   5 Works with qmail 1.01 to 1.03.
