* Added PEP-495-compatible methods to address ambiguous and imaginary dates in time zones in a backwards-compatible way. Ambiguous dates and times can now be safely represented by all dateutil time zones. * Added new methods for working with ambiguous and imaginary dates to the tz module. datetime_ambiguous() determines if a datetime is ambiguous for a given zone and datetime_exists() determines if a datetime exists in a given zone. This works for all fold-aware datetimes, not just those provided by dateutil. * Fixed an issue where dst() in Portugal in 1996 was returning the wrong value in tz.tzfile objects * Fixed an issue where zoneinfo.ZoneInfoFile errors were not being properly deep-copied. * Refactored tzwin and tzrange as a subclass of a common class, tzrangebase, as there was substantial overlapping functionality. As part of this change, tzrange and tzstr now expose a transitions() function, which returns the DST on and off transitions for a given year. * Deprecated zoneinfo.gettz() due to confusion with tz.gettz(), in favor of get() method of zoneinfo.ZoneInfoFile objects. * For non-character, non-stream arguments, parser.parse now raises TypeError instead of AttributeError. * Fixed an issue where tzfile objects were not properly handling dst() and tzname() when attached to datetime.time objects. * /usr/share/lib/zoneinfo was added to TZPATHS for compatibility with Solaris systems. * tzoffset and tzrange objects now accept either a number of seconds or a datetime.timedelta() object wherever previously only a number of seconds was allowed. * datetime.timedelta objects can now be added to relativedelta objects. * Refactored relativedelta.weekday and rrule.weekday into a common base class to reduce code duplication. |
