Make the display of time entirely user definable.
Please note that the term "time" is used here in the generalized sense which includes year (yyyy), month (MM), day (dd), hour (hh), minute (mm), second (ss) & so on.
The time format should be user definable. For example it should be possible to display time in any format and to any resolution. For example, one should be able to display time in the following format:
2.1. yyyy MM dd hh mm ss
