imo using the integer (float for subseconds) unixdate would be preferable, since it easily lends itself to simple processing - like adding 90 seconds without thinking about rolling over to the minute field. or nesting a set of abstractions for minute, hour, day, january, etc.. if pd can't really store the unix timestamp without munging it, that should be fixed.

are you sure about this? i seem to recall matju explaining its 23 bits or so..
