You know that your language's clock/time API's are broken and they are not reliable at all.
So you are not allowed to use any built-in API to access system time/date.
But you also know that your language's ability to perform date math, and retaining a date/time value in a variable are correct.
Write a program that prints the current date/time without calling any date/time/clock API's. For example
GetDate() and similar functions are not allowed.
