The challenge: Create a program that converts a Unix timestamp in N to a list in Ans containing:
{DayOfWeek,Month,Day,Year,Hour,Minute,Second}
Restrictions: This cannot use any timer commands on the 84 plus, and cannot even use dbd(.
Here are a few examples:
N=1234567890
{6,2,13,2009,18,31,30}
N=987654321
{5,4,19,2001,0,25,21}
N=0
{4,12,31,1969,19,0,0}
Bonus points if your program can to the reverse operation; i.e. take a list in L1 and return the number in Ans.
