|
Takes a date, from mysql and returns it in the format specified by the library
|
|
This is less flexible than C4::Date::format_date, which can handle dates of many formats
|
|
if you need that flexibility use C4::Date, if you are just using it to format the output from mysql as
|
|
in circulation.pl use this one, it is much faster.
