In timeless: Fast General Purpose Date/Time Converter
timeless 
A fast general purpose date/time converter written in Rust with crates
dateparser and
chrono.
Installation
You can install the development version of timeless like so:
remotes::install_github("schochastics/timeless")
#or
pak::pak("schochastics/timeless")
the package is also available on CRAN
install.packages("timeless")
library(timeless)
Formats
timeless understands many different date(time) formats out of the box. A
subset is included as a small benchmark dataset.

chronos() is the powerhouse of the package and tries as hard as
possible to parse every input into either a date or a datetime,
depending on out_format. The function can also return a raw character
vector which can be fed into faster converters, such as
fasttime.
chronos(bench_date, out_format = "datetime")

Functions
Under the hood chronos() calls three functions which can also be used
in isolation:
-
parse_datetime(): a fast datetime parser that tries several
different formats until it can parse the input
-
parse_date(): a fast date parser that tries several different
formats until it can parse the input
-
parse_epoch(): a fast-ish epoch timestamp parser
other packages
anytime is the most accepted
general purpose date(time) converter.
It does not recognize all accepted formats of timeless out of the box.
(Note that the unrecognized formats can be added via
anytime::addFormats())

anytime::anytime(bench_date),

The list of formats supported out-of-the-box can be retrieved with
anytime::getFormats(). timeless implements these formats natively
too.
Concerning runtime, timeless seems to be quite a bit faster than
anytime.

Disclaimer:
While it might seem that timeless has an edge over anytime, it is
far less battle tested and mature. Date parsing can be very tricky. I am
grateful for everyone who can take the package for a spin and report
issues.

chronos() is the powerhouse of the package and tries as hard as
possible to parse every input into either a date or a datetime,
depending on out_format. The function can also return a raw character
vector which can be fed into faster converters, such as
fasttime.
chronos(bench_date, out_format = "datetime")

Functions
Under the hood chronos() calls three functions which can also be used
in isolation:
-
parse_datetime(): a fast datetime parser that tries several different formats until it can parse the input -
parse_date(): a fast date parser that tries several different formats until it can parse the input -
parse_epoch(): a fast-ish epoch timestamp parser
other packages
anytime is the most accepted general purpose date(time) converter.
It does not recognize all accepted formats of timeless out of the box.
(Note that the unrecognized formats can be added via
anytime::addFormats())

anytime::anytime(bench_date),

The list of formats supported out-of-the-box can be retrieved with
anytime::getFormats(). timeless implements these formats natively
too.
Concerning runtime, timeless seems to be quite a bit faster than
anytime.

Disclaimer:
While it might seem that timeless has an edge over anytime, it is
far less battle tested and mature. Date parsing can be very tricky. I am
grateful for everyone who can take the package for a spin and report
issues.
