| x | a difftime object. |
| value | a character string specifying the time unit, such as "secs", "mins", "hours", "days", and "weeks". |
| units, units.difftime | returns the units attribute of x. |
| units<-, units<-.difftime | returns a difftime object converted from x with value used as the time unit. |
