let's continue on koha-devel Hum, Koha::DateUtils looks buggy too: use Modern::Perl; use Koha::DateUtils qw( dt_from_string output_pref ); use DateTime; use DateTime::Format::DateParse; my $date_string = '15/06/1800'; # metric in pref my $dt = dt_from_string( $date_string ); say '1 => ' . output_pref( $dt ) if $dt; $dt = DateTime->new(year => 1800, month => 06, day => 15); say '2 => ' . output_pref( $dt ) if $dt; $date_string = '06/15/1900'; $dt = DateTime::Format::DateParse->parse_datetime( $date_string ); say '3 => ' . output_pref( $dt ) if $dt; $dt = DateTime::Format::DateParse->parse_datetime( $date_string, 'Europe/Paris' ); say '4 => ' . output_pref( $dt ) if $dt; Will display: 2 => 15/06/1800 00:00 The problem comes from DateTime::Format::DateParse. Somebody knows why we use this module instead of generating a DateTime object directly from the DateTime module? 2015-01-20 11:18 GMT+01:00 Jonathan Druart <jonathan.druart@biblibre.com>:

Hello Hugo,

You should try to use Koha::DateUtils, instead of C4::Dates. I found some occurrences of "1900" in C4::Dates, maybe there are some stuffs hardcoded in it. We are going to deprecate C4::Dates.

Cheers, Jonathan

Dear all,

We're experiencing problems filling dates before 1900 in Serial startdate, for dats after 1900 it stores fine the date, but for dates before 1900, it stores fine in mysql but in intranet shows the date you filled + 1900,

2015-01-20 10:26 GMT+01:00 Hugo Agud <hagud@orex.es>: then

...

you have for example start date 3725.

We have tried to modiy Dates.pm but without success, any suggestions? we have not been able to find any bug related

thanks you in advance!
