1 E13 s

To help compare orders of magnitude of different times this page lists times between 320 000 years and 3 200 000 years (10¹³ seconds and 10¹⁴ seconds) See also times of other orders of magnitude.

Shorter times
340,000 years -- half-life of curium-248
379 000 years -- time after the Big Bang until cosmic microwave background radiation began
500 000 years -- time since the colonisation of Eurasia by Homo erectus
~700,000 years -- time since last reversal of earth's magnetic field
790 000 years -- age of the earliest evidence of the controlled use of fire by Homo erectus
1,000,000 years -- the average lifespan of a blue supergiant star
1,500,000 years -- time since beginning of Pleistocene Epoch (beginning of Quaternary Period)
1,500,000 years -- time since end of Pliocene Epoch (end of Tertiary Period)
1,530,000 years -- half-life of zirconium-93
2,000,000 years -- duration of the Paleolithic
2,500,000 years -- approximate age of the genus Homo
2,600,000 years -- half-life of technetium-97
