For performance issue multilog binary in daemontools logs in TAI format like following:

@400000004a9b768834d8118c status: local 0/500 remote 4/299

You have to pipe output to tai64nlocal binary to see date in human readable format.  This is being annoying while searching in log files.

We created a small patch to enable human readable logging in multilog via localtime function. The new log lines will look like following:

Sat Dec 19 03:02:51 2009  status: local 0/500 remote 0/299

I belive that some people will not like this idea.  We found it useful and wanted to share with open source community.

The patch is located at http://files.endersys.com/patches/daemontools-0.76-localtime.patch
