How to print out date and time in this format in Lua?

Question

I want to print out the date and time in this format like so

4/25/2017 12:45 PM 

Answer 1

os.date has an optional first argument, format, which is used for formatting date and time. e.g.

print(os.date("%m/%d/%Y %I:%M %p"))
-- 04/25/2017 04:39 PM

The detail of the format specifiers is in C's strftime.
