PC time & date

is there any ways can recognise the PC whether is using 24-hours format or 12-hour (AM/PM) format?

well there's probably a way of checking the system settings using API.

or you could do something like:

VB Code:

If Right$(CStr(Time), 1) = "M" Then
    ' 12 Hour clock
Else
    ' 24 Hour clock
End If

but why does it matter?
