$adate(number)

Documentation for the $time(ctime,format) and $date(ctime,format) and $gmt(ctime,format) syntax are hidden within $asctime's documentation. It would help users if these formats were listed next to the identifier-without-parameters syntax.

$adate(number) could return similar string as $date(number) except in mm/dd/yyyy format.

$adate was added long before the above syntax for $date $time and $gmt were updated to allow optional parameters, so it appears to have been missed when the others had their syntax updated. $adate returns $null or 'no such identifier' when trying to use it with similar syntax to that of $date. I realize the purpose of $adate is to show US date format, so the $2 format string probably doesn't need to be supported, but $adate(number) would be useful.

I see identical output for $fulldate and for $asctime used without using any parameters, so there's probably not the need to extend $fulldate syntax to support $1 number, where currently $fulldate(number) is also an invalid identifier.
