Get Current Date and Time

Description

Sys.time and Sys.Date returns the system's idea of the current date with and without time.

Usage

Sys.time()
Sys.Date()

Details

Sys.time returns an absolute date-time value which can be converted to various time zones and may return different days.

Sys.Date returns the current day in the current timezone.

Value

Sys.time returns an object of class "POSIXct" (see DateTimeClasses). On almost all systems it will have sub-second accuracy: on systems conforming to POSIX 1003.1-2001 the time will be reported in microsecond increments. On Windows it increments in clock ticks (1/60 of a second) reported to millisecond accuracy.

Sys.Date returns an object of class "Date" (see Date).

Note

Sys.time may return fractional seconds, but they are ignored by the default conversions (e.g. printing) for class "POSIXct". See the examples and format.POSIXct for ways to reveal them.

See Also

date for the system time in a fixed-format character string; the elapsed time component of proc.time for possibly finer resolution in changes in time.

Examples

Sys.time()
## print with possibly greater accuracy:
op <- options(digits.secs=6)
Sys.time()
options(op)

## locale-specific version of date()
format(Sys.time(), "%a %b %d %X %Y")

Sys.Date()
