I think you have to subclass Formatter.formatTime(). Here's a monkey- patching session to get you started: >>> import logging >>> logging.basicConfig(format="%(asctime)s") >>> logging.getLogger().error("foo") 2012-07-20 16:17:39,364 >>> _formatTime = logging.Formatter.formatTime >>> def formatTime(*args): ... return _formatTime(*args).replace(",", ".") ... >>> logging.Formatter.formatTime = formatTime >>> logging.getLogger().error("foo") 2012-07-20 16:20:20.838 See also http://docs.python.org/dev/py3k/library/logging.html#logging.Formatter.formatTime """ Changed in version 3.3: Previously, the default ISO 8601 format was hard- coded as in this example: 2010-09-06 22:38:15,292 where the part before the comma is handled by a strptime format string ('%Y-%m-%d %H:%M:%S'), and the part after the comma is a millisecond value. Because strptime does not have a format placeholder for milliseconds, the millisecond value is appended using another format string, '%s,%03d' – and both of these format strings have been hardcoded into this method. With the change, these strings are defined as class-level attributes which can be overridden at the instance level when desired. The names of the attributes are default_time_format (for the strptime format string) and default_msec_format (for appending the millisecond value).
