 /*Function to get Current Date*/
/* EXPLANATION FOR WHY 38
Fortunately there is a simple solution to this extremely complex problem. 
Since it is supported by all browsers, always use getYear(). 
Divide the outcome by 100 and take the modulus, so that now we have a number from 0 to 99. 
If this number is smaller than 38, add 2000, if it's larger add 1900. This always gives the correct year.
So always use the function below when you have to calculate a year:
(Why 38? Because Epoch Time will end in 2038. You can also use 
(y > 69) ? 1900: 2000;
because in the Epoch Time system no date can be before 1970).
