Method: Time#to_f

Defined in:
time.c

#to_f ⇒ Float

Returns the value of time as a floating point number of seconds since the Epoch.

t = Time.now
"%10.5f" % t.to_f   #=> "1270968744.77658"
t.to_i              #=> 1270968744

Note that IEEE 754 double is not accurate enough to represent the number of nanoseconds since the Epoch.

Returns:
