Version 1.4 of dateutil is out: http://labix.org/python-dateutil Changes since 1.3 ----------------- - Fixed another parser precision problem on conversion of decimal seconds to microseconds, as reported by Erik Brown. Now these issues are gone for real since it's not using floating point arithmetic anymore. - Fixed case where tzrange.utcoffset and tzrange.dst() might fail due to a date being used where a datetime was expected (reported and fixed by Lennart Regebro). - Prevent tzstr from introducing daylight timings in strings that didn't specify them (reported by Lennart Regebro). - Calls like gettz("GMT+3") and gettz("UTC-2") will now return the expected values, instead of the TZ variable behavior. - Fixed DST signal handling in zoneinfo files. Reported by Nicholas F. Fabry and John-Mark Gurney. What is it? ----------- The dateutil module provides powerful extensions to the standard datetime module, available in Python 2.3+. Features -------- * Computing of relative deltas (next month, next year, next monday, last week of month, and a lot more); * Computing of relative deltas between two given date and/or datetime objects; * Computing of dates based on very flexible recurrence rules (every month, every week on Thursday and Friday, every Friday 13th, and a *LOT* more), using a superset of the iCalendar RFC specification. Parsing of RFC strings is supported as well. * Generic parsing of dates in almost any string format; * Timezone (tzinfo) implementations for tzfile(5) format files (/etc/localtime, /usr/share/zoneinfo, etc), TZ environment string (in all known formats), iCalendar format files, given ranges (with help from relative deltas), local machine timezone, fixed offset timezone, UTC timezone, and Windows registry-based timezones. * Internal up-to-date world timezone information based on Olson's database. * Computing of Easter Sunday dates for any given year, using Western, Orthodox or Julian algorithms; * More than 400 test cases. -- Gustavo Niemeyer http://niemeyer.net
