So I ran

    $ git config log.date  "format:%Y-%m-%d %H:%M"
    $ git config --list |grep log.date
    log.date=format:%Y-%m-%d %H:%M

Then I have a script as
  $ cat script.sh
  #!/bin/sh

  git log >out

after executing I get:

  $ head out

Also gitk seems to work here.

Rene's answer sounds reasonable,
check the version(s) of Git on your system?
