parseDatetimetz

✓ from zope.datetime import parseDatetimetz

✗ from zope.datetime import parse_datetime

Function name uses CamelCase

RFC850

✓ from zope.datetime import RFC850

✗ from zope.datetime import rfc850

Constant name is uppercase

ZoneInfo

✓ from zope.datetime import ZoneInfo

✗ from zope.datetime import Timezone

Class name is ZoneInfo not Timezone

Parse datetime strings using common formats.

from zope.datetime import parseDatetimetz from datetime import datetime # Parse an HTTP-date (RFC 1123) dt = parseDatetimetz('Mon, 27 Apr 2026 12:00:00 GMT') print(dt) # timezone-aware datetime # Parse a datetime with timezone offset dt2 = parseDatetimetz('2026-04-27T12:00:00+02:00') print(dt2)

Debug

Known issues

breakingVersion 6.0 requires Python >=3.9 and may have changed internal timezone handling. Code relying on pytz objects might break if now using zoneinfo.

fix

Ensure compatibility: if using pytz, convert to zoneinfo or keep using pytz, but test edge cases.

affects: >=6.0

gotchaFunction parseDatetimetz does NOT parse all ISO 8601 strings; it only handles a subset (RFC 2822, RFC 850, ANSI C, and a few others).

fix

Use dateutil.parser.isoparse or datetime.fromisoformat for general ISO 8601 parsing.

affects: all

deprecatedThe module zope.datetime may be considered legacy; for new projects consider using dateutil or built-in zoneinfo (Python 3.9+).

fix

Migrate to dateutil or built-in module.

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'zope.datetime'

Package installed as 'zope-datetime' but import path is 'zope.datetime'.

fix

Install the correct package: pip install zope-datetime

AttributeError: module 'zope.datetime' has no attribute 'parse_datetime'

Function name is parseDatetimetz (CamelCase), not parse_datetime.

fix

Use: from zope.datetime import parseDatetimetz

ValueError: unknown timezone offset

Parsing a timezone offset like 'Europe/Berlin' that isn't an integer offset.

fix

The function parseDatetimetz only handles ±HHMM offsets, not named timezones. Pre-process with pytz or zoneinfo.
