I need to figure out the math forumula for converting the numbers on the left to the dates on the right.
There's another trick, the date order might be different. The 139 might be the year since none of those number changed, and only the year stayed the same.
Anyone pro enough to see a pattern? Even more pro to know the answer?

No math formula needed... they're Unix timestamps. Just pass the values to [man]date/man in the second parameter.

For further development of the idea, the "math formula" is built into the [man]date[/man] function; the timestamp simply counts the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC.
