Greetings,
Do you mean XA40? I don't think an AX40 exists.
XA40 User Guide
Page 72 talks about setting a User Bit which includes date and time. It only works on clips filmed in XF-AVC format and only to internal memory. It does not appear to work with SD Cards. It may be different for external displays connected to HDMI out but I couldn't find information about this.
You can all Canon as well. They are happy to answer questions and help.
