v0.2.1

Summary: v0.2.1 of dateutils

This is dateutils v0.2.1.

This is a bug fix and feature release.

The dadd tool now supports mass-adding durations (from stdin). The ddiff tool is now time zone aware. A new tool dround is added to round dates or times or date-times to the next occurrence of what’s given as round-spec.

Bug fixes:

See info page examples and/or README.

v0.2.0

Summary: v0.2.0 of dateutils

This is dateutils v0.2.0.

This is a feature release.

The distinction between binaries for date, time and date-time processing is cleared up by a unified set of tools, prefixed with d.

Thus: dadd + tadd -> dadd dconv + tconv + dtconv -> dconv ddiff + tdiff -> ddiff dgrep + tgrep -> dgrep dseq + tseq -> dseq dtest + ttest -> dtest

Furthermore, all tools now fully cope with dates, times and date-times. Virtual timezones have been added (use GPS or TAI).

See info page examples and/or README.

v0.1.10

Summary: v0.1.10 of dateutils

This is dateutils v0.1.10.

This is a bug fix release.

  • account for big-endian machines
  • GNUisms (mempcpy() and getline()) are removed
  • inf-loop in tseq is fixed (bug #6)
  • nanoseconds are preserved upon time zone conversion

See info page examples and/or README.

v0.1.9

Summary: v0.1.9 of dateutils

This is dateutils v0.1.9.

This is a bug fix release.

The code for date addition is refactored, with it a new duration type is introduced, DT_MD, to capture larger month and day summands.

See info page examples and/or README.

v0.1.8

Summary: v0.1.8 of dateutils

This is dateutils v0.1.8.

This is a bug fix release.

A bit fiddling bug gave erroneous results in dconv now.

Furtherly, date expressions (for dgrep et al.) can now be arbitrarily joined with conjunctions (&&) and disjunctions (||) as well as negations (!).

See info page examples and/or README.

v0.1.7

Summary: v0.1.7 of dateutils

This is dateutils v0.1.7.

This is a bug fix release.

Most notably, sloppy date arithmetics have been replaced by correct ones, e.g. 2100 is not longer a leap year and the 31st of Feb is instantly corrected to 28/29 Feb.

Furtherly, the unmaintainable idea of dedicated duration types has been replaced with overloaded dt_d_s types with the side-effect that adding days or business days to dates now works and ymcw dates can be properly compared.

See info page examples and/or README.

v0.1.6

Summary: v0.1.6 of dateutils

This is dateutils v0.1.6.

This is a feature release.

The dcal and tcal binaries are renamed to dconv and tconv respectively, there has been a naming conflict with the tcal binary from the gcal package. Thanks to ulm (https://github.com/ulm) for pointing this out.

Changes in behaviour: Furthermore, many numerical specifiers now cope with the th flag to denote ordinals: %dth %b %Y applied to 2011-10-03 will yield 3rd Oct 2011.

business days can be denoted by suffixing them with b both in the input and the specs, the b modifer like the th modifier are suffixes and serve formatting and notation purposes.

Also, many gnu-isms are removed to facilitate *BSD builds.

See info page examples and/or README.

v0.1.5

Summary: v0.1.5 of dateutils

This is dateutils v0.1.5.

This is a feature release. Grep-like utilities have been added.

  • dgrep like grep for date values
  • tgrep like grep for time values
  • ttest like test for time values
  • tcal like dcal for time values

Changed behaviour: Utilities in sed-mode will repeat the whole line if nothing on the line matches instead of writing a warning.

See info page examples and/or README.

v0.1.4

Summary: v0.1.4 of dateutils

This is dateutils v0.1.4.

This is a feature release. Utilities to deal with times have been added.

  • tseq like dseq for time values
  • tadd like dadd for time values
  • tdiff like ddiff for time values

See info page examples and/or README.

Man pages have an author now and most of the format specs are documented, at least the specs we do not plan to change.

v0.1.3

Summary: release v0.1.3 of dateutils

This is dateutils v0.1.3.

This is a feature and convenience release. Most importantly, the project is now called dateutils. All tools are documented now (to some degree) and have their own tests.

v0.1.2

Summary: release v0.1.2 of datetools

This is datetools v0.1.2.

This is a feature release. The dseq tool is now entirely in the hand of our internal date library. Furthermore, dseq now accepts negative increments and dates where FIRST > LAST. Hereby the increment argument has an overloaded meaning: If INCREMENT is negative but FIRST < LAST then compute the beginning instead of the end.

dseq 2000-01-01 -34 2000-03-31
=>
  2000-01-23
  2000-02-26
  2000-03-31

as opposed to

dseq 2000-01-01 34 2000-03-31
=>
  2000-01-01
  2000-02-04
  2000-03-09

Likewise, FIRST can be newer than LAST and with a negative increment, the end is variable whereas a positive increment leaves the beginning variable.

v0.1.1

Summary: release v0.1.1 of datetools

This is datetools v0.1.1.

This is a clean up release with the long-term aim to outsource all functionality into a library. Two new command line tools have undergone this transition, dcal and dtest.

The overall goal is to have all tools using a common set of command line options, -i or –input-format to specify one or more input formats to be tried and -f or –format to specify an output format if applicable.

v0.1.0

Summary: release v0.1.0 of datetools

This is datetools v0.1.0.

This is the first working version of datetools comprising two command line tools, dseq and strptime.
