I have been setting up the SharePoint Room Equipment and Reservations Template for use in the college as a bookings system for ICT Rooms, Minibuses, Halls and Meeting Rooms. Came across an annoyance where when selecting a time period in the day, the form would automatically fill in the date in American format (mm/dd/yyyy).
All of the locale settings on the server and the client had been set to UK English.
Turns out that the locale is hard coded in that page. To edit,
1. Go to the Reservations Page, and select Site Actions –> Edit Page
2. Modify the Gantt Chart web part.
3. Select XSL Editor.
4. Near the top you will find a line like this:
<xsl:param name=”lcid”>1033</xsl:param>
Replace it with
<xsl:param name=”lcid”>5129</xsl:param>
Save your changes and your form will now work in UK date format.
