Use xts.

Specify a POSIXlt index

All of the properties will be available in POSIXlt.

However, you didn't state what you wish to accomplish.  It is likely 
that xts will be able to subset anything you need without splitting 
things up.

Realize that using a real time series class will always perform better 
than using a data frame.

Cross-posting is considered rude. If you need more help than the above, 
please make your query specific to some problem in finance, to keep the 
list focused on its topic (finance), or only reply to r-help.

It would be polite to sign your name too...
