Here's the solution in case anyone else searches this. This is probably not the most elegant way, but it seems to work.
var bool AMorPM=(Contains(ToText(ToTimeOfDay([My DateTime Field])),"PM")=true); //Is this AM or PM
var text NewDate=(ToText(ToDate([My DateTime Field]))); //Convert Timestamp to Date only
var text NewHour=Right(Left(ToText(ToTimeOfDay([My DateTime Field])),":")," "); //Get Hour
var text NewMinute=Left(Right(ToText(ToTimeOfDay([My DateTime Field])), ":")," "); //Get Minute and Trim off AM/PM
var text TwentyFourHour= //Correct Hour if PM
Case($NewHour,
"12", "12",
"1", "13",
"2", "14",
"3", "15",
"4", "16",
"5", "17",
"6", "18",
"7", "19",
"8", "20",
"9", "21",
"10", "22",
"11", "23");
var text TwelveHour= //Correct Hour if AM
Case($NewHour,
"12","00",
"1", "01",
"2", "02",
"3", "03",
"4", "04",
"5", "05",
"6", "06",
"7", "07",
"8", "08",
"9", "09",
"10", "10",
"11", "11");
If($AMorPM=true,
$NewDate&" "&$TwentyFourHour&":"&$NewMinute,
$NewDate&" "&$TwelveHour&":"&$NewMinute
)
