# A Trillion Year Clock.

I created a clock that runs to 2,147,483,647 Trillion years,
at which point it will roll over to 0. BIGBANG, EEPROM, CURRENT TIME, included.

(At least in software)
If you need something longer, then you need to write it down on a piece of paper.

Connect putty to your propeller's p30/p31 debug output.

In 2015, the Planck Collaboration estimated the age of the universe to be 13.813±0.038 billion years,

slightly higher but within the uncertainties of the earlier number derived from the WMAP data.

By combining the Planck data with external data, the best combined estimate of the age of the universe is:

(13.799±0.021)×10^9 years old.

13,799,792,018.342.15.51.42 years old.

13,799,000,000 = (13.799±0.021)×10^9

790,000 = Fudge number. Speed of light is 299,792,458, so i stole from its middle.

2018 = Our year.

Countdown timer since beginning of 2018, update yours to match.

Now none of us can use the excuse our clocks are wrong.

How to view output.

Get PUTTY, because the serial output has ANSI command codes.

P31 and P30 are the TX/RX port for serial communication.

You better be ready for speed, it dumps the clock at 921,600 baud.
