The format of the time information output in the application log can be changed with [Layout].
The default value is "[%c]% m [% d {HH: mm: ss}]% n".
If you want to output the date and time (up to milliseconds), you can use "[%c]% m [yyyy /MM/dd HH: mm: ss, SSS}]% n".
*yyyy: year MM: month dd: day HH: hour mm: minute ss: second SSS: milliseconds.
Sample output: 2019/02/08 10:05:25,115
