|

SL::DB::Helper::AccountingPeriod - Helper functions for calculating dates relative to the financial year
|
|||
=head1 FUNCTIONS
|
|||
=over 4
|
|||
=item C<get_balance_starting_date $date>
|
|||
Given a date this method calculates and returns the starting date of the
|
|||
financial period relative to that date, according to the configured
|
|||
balance_startdate_method in the client configuration. The returned date is
|
|||
locale-formatted and can be used for SQL queries.
|
|||
If $date isn't a DateTime object a date string is assumed, which then gets
|
|||
date-parsed.
|
|||
If no argument is passed the current day is assumed as default.
