The Planck time is the time it would take a photon travelling at the speed of light to cross a distance equal to the Planck length(. This is the "quantum of time", the smallest measurement of time that has any meaning. Within the framework of the laws of physics as we understand them today, we can neither measure nor discern any difference between the universe at the time it first came into existence and the universe anything less than 1 Planck time later.
The estimated age of the Universe (4.3 × 1017 s) is roughly 8 × 1060 Planck times. (Wikipedia)


Orders of magnitude (time)
From Wikipedia, the free encyclopedia.

1 yoctosecond
1 zeptosecond
1 attosecond
1 femtosecond
1 picosecond
1 nanosecond
1 microsecond
1 millisecond ~ blink of an eye ~ 50 to 80 ms
1 second ~ minute = 60 s
1 kilosecond(16.7 minutes) ~ hour = 3600 s day = 86 400 s = 86.4 ks week = 604.8 ks
1 megasecond(11.6 days) ~ month = 2.6 x 106 s year = 31.6 Ms ~= π x 107
1 gigasecond(32 years) ~ century = 3.16 Gs ~= π x 109 s millennium = 31.6 Gs ~= π x 1010 s
1 terasecond(32 000 years)
1 petasecond(32 million years)
1 exasecond(32 billion years)
