> - Network transfer speed
> - Additional installed packages (re-configuration, upgrading components...)

> field?
> There would not be very helpful - and not worth the programming and maintaining
> effort. Especially since it implies modifying the XML structure as well.

> However that does not mean that I am against wpkg.js <-> WPKG client

> 2008-01-12 20:30:00 - WPKGSTATUS Starting software synchronization
> 2008-01-12 20:30:02 - WPKGSTATUS Tasks: INSTALL 3; UNINSTALL 2
> 2008-01-12 20:30:03 - WPKGSTATUS Removing package: Mozilla SeaMonkey
> 2008-01-12 20:32:00 - WPKGSTATUS Removing package: QuickTime Lite
> 2008-01-12 20:32:00 - WPKGSTATUS Installing package: Mozilla FireFox
> 2008-01-12 20:33:30 - WPKGSTATUS Installing package: QuickTime Alternative
> 2008-01-12 20:35:00 - WPKGSTATUS Installing package: WinMerge
> 2008-01-12 20:36:10 - WPKGSTATUS Finished software synchronization

Hi This looks totally ok with me. If i understand it correctly it counts the
actual time that has gone with the installation(s)
