Just to complete the discussion on date parsing, unclass(as.POSIXct(strptime(date(),"%c"))) or as.POSIXct(strptime(date(),"%c")) - structure(0,class="POSIXct") gives the time in seconds since the beginning of time() (generally Jan 1 1970 0:00:00 GMT on Unixen).
It is easier to use unclass(Sys.time()), which gives this directly. The base is always `the epoch', as given by Peter. Unless your clock is set wrong (possible) that should be the correct value, the problem being the conversions done in printing it.
However, I think proc.time()[3] is more relevant for your needs.
It is higher accuracy too (ca 0.01 secs).
