difftime_dtc: Time Differences for Date/Time Objects

In rpkyle/cscmisc: Miscellaneous Data Manipulation and Simulation Tools

Description

This function takes two date-time objects, with or without date separator, and estimates the time difference between them.

Usage

difftime_dtc(date1, date2, units, tz, as.real)

Arguments

date1	A date, a character string in date-time format.
date2	A second date, a character string in date-time format.
units	Units for calculation, defaults to hours.
tz	Time-zone, defaults to "UTC".
as.real	Boolean; should result be returned as a real number?

Details

The function allows for date-time objects of class character or POSIXct/POSIXlt; it will convert either or both inputs to POSIX-compliant objects as required.

The result is returned as a numerical difference (real number), or as a difftime object.

Value

Either a numeric value corresponding to the time difference between the inputs, or a difftime object.
