Oracle DATE/TIME COMVERSIONS

Question

Hi guys!
This is my second thread about formating a date variable.
The fact is I would like to increment a date variable in an amount of miliseconds, and after that I want to format the date to this way dd/mm/yyyy 24hh:mmi.
An example:
Date Variable Miliseconds to increment Date Resut
3/13/2007 8:17:28 170000 13/03/2007 08:20
I also want to convert an amount of miliseconds to a Time Variable (In this case date Variable) to this way 24hh:mi
An example:
Miliseconds Time Result
170000 00:02
I hope you can help me guys.
Thanks.

Miss read
Milliseconds you can convert to seconds by dividing 1000
