@jackylk CARBON_TIMESTAMP_MILLIS is more precise in terms of time as
compared to CARBON_TIMESTAMP_DEFAULT_FORMAT.
Also, there were three formats defined for TIMESTAMP in
CarbonCommonConstants
1) String CARBON_TIMESTAMP_DEFAULT_FORMAT = "yyyy-MM-dd HH:mm:ss"; (It has
maximum occurences in the project currently)
2) String CARBON_TIMESTAMP = "dd-MM-yyyy HH:mm:ss";
3) String CARBON_TIMESTAMP_MILLIS = "dd-MM-yyyy HH:mm:ss:SSS";
Do you want to use one format at all places? If yes, please suggest me one
format from the three available formats.
