-\r
-=head1 DESCRIPTION\r
-\r
-This module automatically inflates/deflates DateTime objects\r
-corresponding to applicable columns. Columns may also be\r
-defined to specify their nature, such as columns representing a\r
-creation time (set at time of insertion) or a modification time\r
-(set at time of every update).\r
-\r
-=head1 METHODS\r
-\r
-=head2 register_column\r
-\r
-This method will automatically add inflation and deflation rules\r
-to a column if an epoch value has been set in the column's definition.\r
-If the epoch value is 'ctime' (creation time) or 'mtime'\r
-(modification time), it will be registered as such for later\r
-use by the insert and the update methods.\r
-\r
-=head2 insert\r
-\r
-This method will set the value of all registered creation time\r
-columns to the current time. No changes will be made to a column\r
-whose value has already been set.\r
-\r
-=head2 update\r
-\r
-This method will set the value of all registered modification time\r
-columns to the current time. This will overwrite a column's value,\r
-even if it has been already set.\r
