Subject RE: Log timestamp in UTC
Date Wed, 08 Dec 2004 13:15:24 GMT
There are a number of guidelines regarding the issues of the DateTime


The best practice appears to be to store the DateTime as UTC and convert
to local time where necessary, i.e. in display or for serialisation.
This is something we will need to look at. In the meantime I have added,
to CVS, support for outputting the UTC date from the PatternLayout.
