There have been no assumptions made as to what RDBMS you will be using. As per the note in the DBIx::Class::InflateColumn::DateTime documentation, you will need to install the DateTime::Format::* module that matches your RDBMS of choice.


This module automatically inflates/deflates DateTime objects from/to epoch values for the specified columns. This module is essentially an extension to DBIx::Class::InflateColumn::DateTime so all of the settings, including "locale" and "timezone", are also valid.

A column will be recognized as an epoch time given one of the following scenarios:

  • "data_type" is an "int" of some sort and "inflate_datetime" is also set to a true value
  • "data_type" is some other value (e.g. "varchar") and "inflate_datetime" is explicitly set to "epoch".

DBIx::Class::TimeStamp can also be used in conjunction with this module to support epoch-based columns that are automatically set on creation of a row and updated subsequent modifications.


add_columns( )

Provides backwards compatibility with the older DateTime::Epoch API.

_inflate_to_datetime( )

Overrides column inflation to use "Datetime->from_epoch".

_deflate_from_datetime( )

Overrides column deflation to call "epoch()" on the column value.
