the optional datefmt argument. If datefmt is omitted, you get an

ISO8601-like (or RFC 3339-like) format.

Use a style parameter of '%', '{' or '$' to specify that you want to

use one of %-formatting, :meth:`str.format` (``{}``) formatting or

in formatters to provide for any specific requirement, but the

basic behaviour is as follows: if datefmt (a string) is specified,

it is used with time.strftime() to format the creation time of the

record. Otherwise, the ISO8601 format is used. The resulting

string is returned. This function uses a user-configurable function

to convert the creation time to a tuple. By default, time.localtime()

is used; to change this for a particular formatter instance, set the

'converter' attribute to a function with the same signature as

time.localtime() or time.gmtime(). To change it for all formatters,

for example if you want all logging times to be shown in GMT,
