If you are using 'difftime', you can specify the units:
> x <- as.POSIXct(c('2009-01-01 10:00', '2009-03-04 13:00'))
> x
[1] "2009-01-01 10:00:00 GMT" "2009-03-04 13:00:00 GMT"
> difftime(x[2], x[1])
Time difference of 62.125 days
> difftime(x[2], x[1], units='secs')
Time difference of 5367600 secs
