Fix logging date format to avoid parse error

When MDCSetup class in logging-filter-base tries to calculate an elapsed
time, it expects a datetime is given in ISO format.
But date format in LogFieldsMdcHandler is not compatible with ISO format
therefore 'Unable to calculate elapsed time due to error' occurs.

This change fixes date format in the class
so that the date string can be parsed by logging-filter.
