Dates not localized
there are many places,tools that displays time and/or date not being localized. For example : glosary, history training session(s) time limitation, session category time limitation, ....
return $date->format('Y-m-d H:i:s');
from method api_get_local_time (internatinalization.lib.php)
may i suggest to browse for the files for using api_get_local_time without being wrapped by method for eq. api_format_date from the same library ?
just one case is shown on the image attached
