new_difftime: Create a difftime object.

Description

new_difftime creates a difftime object with the specified number of units. Entries for different units are cumulative. difftime displays durations in various units, but these units are estimates given for convenience. The underlying object is always recorded as a fixed number of seconds. For display and creation purposes, units are converted to seconds using their most common lengths in seconds. Minutes = 60 seconds, hours = 3600 seconds, days = 86400 seconds, weeks = 604800. Units larger than weeks are not used due to their variability.

Usage

new_difftime(...)

Arguments

...

a list of time units to be included in the difftime and their amounts. Seconds, minutes, hours, days, and weeks are supported.

Value

a difftime object

Details

difftime objects are durations. Durations are time spans measured in seconds. They measure the exact passage of time but do not always align with measurements made in larger units of time such as hours, months and years. This is because the length of larger time units can be affected by conventions such as leap years and Daylight Savings Time. lubridate provides a second class for measuring durations, the duration class.

Examples

Run this code

new_difftime(second = 90)
# Time difference of 1.5 mins
new_difftime(minute = 1.5)
# Time difference of 1.5 mins
new_difftime(second = 3, minute = 1.5, hour = 2, day = 6, week = 1)
# Time difference of 1.869201 weeks
new_difftime(hour = 1, minute = -60)
# Time difference of 0 secs
new_difftime(day = -1)
# Time difference of -1 days
