Public Member Functions
	time (sec_t sec=0, usec_t usec=0)
	Initializes the time at (0, 0)

Constructor & Destructor Documentation

jafar::ddf::time::time

(

timeval const &

t

)

[inline, explicit]

Initializes the time using the given time structure We assume that t is already well-formed (i.e.

the microsecond count is no more than UsecPerSec)

Member Function Documentation

static time jafar::ddf::time::infty

(

)

[inline, static]

A special time object handled as "infty".

• infty < a and a > infty return false
• infty > a and a < infty return true
• a - now = a
• now - a is undefined (even if a == now)
• a + now = a
