Release Notes: This is a bugfix release. The code for date addition is refactored, and with it a new duration type, DT_MD, is introduced to capture larger month and day summands. See the info page examples and/or README.
Release Notes: -q|--quiet no longer sends some commands into an infinite loop. NetBSD test failures (due to missing leap seconds) were fixed. AIX builds are now supported (getopt_long() is part of the code now). Internally, the test harness was migrated to the cli-testing tool. This fixes an issue when tests are run in directories with odd names (spaces, dollar signs, etc. in the path name).
Release Notes: This release fixes issue 18 (long inputs to a short specifier string will yield an error), consuming zone specs (1,200+) in the input via the %Z specifier, and ddiff's stdin stamps undergoing conversion according to --from-zone. It cleans up the distribution for inclusion in Debian.
Release Notes: This is a bugfix release. It adds the special output formats "jdn" and "ldn" for julian/lilian day numbers. Multiple occurrences of date/times within one line are now all processed rather than only the first occurrence. A zone difference specifier (%Z) is now supported for parsing and printing. The matlab zone converter tzconv has been added. Building with icc 13 works now. Many gcc warnings are fixed.
Release Notes: This is a bugfix and feature release. For features, ISO 8601 week dates are now first class objects (of type DT_YWD), a %rY specifier denotes years in calendars which deviate from the Gregorian year, and dgrep now accepts shorthand inputs (today, now, etc.) and inputs as specified by -i. For bugfixes, dadding months and years to YMCW dates now works, zoneinfo files with only transitions in the past are handled properly (bug #10), and dseq with just one argument works properly (story #36051287).
Release Notes: Olson's zoneinfo database files are now checked for at configure time. leap-aware calculations use the shipped leapseconds file. ddiff and dadd can take leap-second transitions into account. ddiff no longer segfaults when run without arguments. dadd now copes with huge summands and works with ymcw dates. An error in ddiff with negative differences was fixed.
