Using a derived field to output time in 24-hour format

Problem or error: How do I output time in 24-hour format (military time) in Campaign?

Solution: To obtain 24-hour time format you can create a derived field in Campaign using the following statement.

if((string_seg(10, 11, Current_Time()) = 'PM' 
AND number(string_seg(1, 2, Current_Time()))< 12) , 
string_concat(format((number(string_seg(1, 2, Current_Time()))+ 12),2), 
string_seg(3, 8, Current_Time())), 
if ((string_seg(10, 11, Current_Time()) = 'AM' 
AND number(string_seg(1, 2, Current_Time())) = 12), 
string_concat('00', string_seg(3, 8, Current_Time())), 
string_concat(string_seg(1, 2, Current_Time()), 
string_seg(3, 8, Current_Time()))))

Note: This example assumes that the hours are formatted with a leading zero (01:01:53 PM and not 1:01:53 PM). The Windows operating system may not provide the leading zero, but UNIX does.

Here is an alternative method that achieves the same result.

StripHour = string_seg(1, 2, Current_time())
HourNum = number(StripHour)
StripPM = string_seg(10, 11, Current_time())
StripRest = string_seg(3, 8, Current_time())
if((StripPM = 'PM' AND HourNum < 12), 
string_concat(format((HourNum + 12),2), StripRest),
if ((StripPM = 'AM' AND HourNum = 12), string_concat('00', StripRest),
string_concat(Strip_Hour, StripRest)
