dhms: A simple class for storing, printing and calculating on time...

In qgeissmann/dhms: Time in Days, Hours, Minutes and Seconds

Description

It derives from numeric and internally represents time in "seconds". Conceptually very close to hms::hms, but with day values and arithmetics operations. Supports construction from formatted string, coercion to and from various data types. Can be used as a regular column in a data frame.

Usage

dhms(seconds = NULL, minutes = NULL, hours = NULL, days = NULL)

as.dhms(x, ...)

## Default S3 method:
as.dhms(x, ...)

## S3 method for class 'difftime'
as.dhms(x, ...)

## S3 method for class 'numeric'
as.dhms(x, ...)

## S3 method for class 'character'
as.dhms(x, ...)

## S3 method for class 'dhms'
as.character(x, ...)

## S3 method for class 'dhms'
format(x, ...)

## S3 method for class 'dhms'
print(x, ...)

Arguments

seconds, minutes, hours, days	Time since ZT0. No bounds checking is performed.
x	An object.
...	Arguments passed on to further methods.

Details

For dhms, all arguments must have the same length or be NULL. Odd combinations (e.g., passing only seconds and hours but not minutes) are rejected.

Examples

print(c(dhms(56, 34, 12),dhms(56, 34, 12)))
dhms(56, 34, 12,1)
as.dhms(3600 * 2 + 60* 23+ 59 )
as.dhms("-1d 12:34:56")[1]
as.dhms(Sys.time())
dhms(102031) - "20:00:00"
dhms(20) == "00:00:20"
dhms(21) > "00:00:20"
dhms(19) < "00:00:20"
print(as.dhms("0.5d"))
print(-dhms(56, 34, 12,1))
## Not run: 
# we expect ERRORS in the folowing cases
as.dhms("0.5d 21:00:00") # decimal days and hours
as.dhms("1d 64:00:00") # more than 24h, and days

## End(Not run)
