1 E17 s: Information from Answers.com

To help compare orders of magnitude of different times this page lists times between 10¹⁷ seconds and 10¹⁸ seconds (3.2 and 32 billion years) See also times of other orders of magnitude.

4.32 billion years: one kalpa, or half a day in the lifetime of Brahma, in Hindu mythology. ^[1]
10 billion years: expected main sequence lifetime of a G2 dwarf star (like the Sun)

Elapsed time

3.9 to 4.1 billion years: age of oldest cellular life (cyanobacteria)
3.7 to 3.9 billion years: age of the Mare Imbrium, the Lower Imbrian epoch
4.5 billion years: age of the Earth (see: Precambrian)
13.2 billion years: age of the oldest known star, HE 1523-0901
13.7 ± 0.2 billion years (4e17 seconds): estimated age of the universe according to the Big Bang theory

3.6 billion years: estimated time until Neptune's moon Triton will fall through the planet's Roche sphere, potentially disintigrating into a new planetary ring system.
5.4 billion years: time before the Sun becomes a red giant
20 billion years: time until the end of the universe in the Big Rip scenario
