Copied from arduino.cc:

micros() will overflow after approximately 70 minutes.
On 16 MHz Arduino boards (e.g. Duemilanove and Nano),
this function has a resolution of four microseconds
(i.e. the value returned is always a multiple of four).
On 8 MHz Arduino boards (e.g. the LilyPad),
this function has a resolution of eight microseconds.
