Python:

This function must have the following header: def my_datetime(num_sec). This function takes in an integer value that represents the number of seconds since the epoch: January 1st 1970. The function takes num_sec and converts it to a date and returns it as a string with the following format: MM-DD-YYYY. It has the following specifications:

• It may be assumed that num_sec will always be an int value
• It may be assumed that num_sec will always be a non-negative value
• Must be able to handle leap years

Some examples:

• my_datetime(0) returns 01-01-1970
• my_datetime(123456789) returns 11-29-1973
• my_datetime(9876543210) returns 12-22-2282
• my_datetime(201653971200) returns 02-29-8360

Your function handle all the computation itself. You are not permitted to use any library that can convert seconds to a date. This includes, but is not limitted to:

• datetime
• arrow
• moment
