I have read through the instructions regarding the Ajax.properties files for changing from mm/dd/yyyy to dd/mm/yyyy.
However I have created an Ajax_en_gb.properties, with the correct settings and restarted using zmcontrol stop then start.
This now uses the 24hr time that I required, however the month/day are still the wrong way round when I am creating an appointment in the calendar.
So I then used the Ajax.properties file and made the changes there (I made a backup) restarted using zmcontrol.
However this also doesn't seem to have had any effect.
Can anyone point me in the correct direction to solve this problem.
