Convert to a duration

You generally convert to a duration from either a sys-time or a naive-time. The precision of the input is retained in the returned duration.

To round an existing duration to another precision, see duration_floor().

Usage

as_duration(x, ...)

Arguments

x

[object]

An object to convert to a duration.

...

These dots are for future extensions and must be empty.

Value

A duration with the same precision as x.

Examples

x <- as_sys_time(year_month_day(2019, 01, 01))

# The number of days since 1970-01-01 UTC
as_duration(x)
#> <duration<day>[1]>
#> [1] 17897

x <- x + duration_seconds(1)
x
#> <sys_time<second>[1]>
#> [1] "2019-01-01T00:00:01"

# The number of seconds since 1970-01-01 00:00:00 UTC
as_duration(x)
#> <duration<second>[1]>
#> [1] 1546300801
