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, possibly microseconds or better. On Windows it increments in clock ticks (usually 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.

Sys.time()

op <- options(digits.secs=6)
Sys.time()
options(op)

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

Sys.Date()
