SQLAlchemy-Utc 0.9.0

SQLAlchemy type to store aware datetime values

SQLAlchemy-Utc

This package provides a drop-in replacement of SQLAlchemy’s built-in DateTime type with timezone=True option enabled. Although SQLAlchemy’s built-in DateTime type provides timezone=True option, since some vendors like SQLite and MySQL don’t provide timestamptz data type, the option doesn’t make any effect on these vendors.

UtcDateTime type is equivalent to the built-in DateTime with timezone=True option enabled on vendors that support timestamptz e.g. PostgreSQL, but on SQLite or MySQL, it shifts all datetime.datetime values to UTC offset before store it, and returns always aware datetime.datetime through result sets.

Long story short, UtcDateTime does:

• take only aware datetime.datetime,

• return only aware datetime.datetime,

• never take or return naive datetime.datetime,

• ensure timestamps in database always to be encoded in UTC, and

• work as you’d expect.
