Continue having a tor_gmtime_impl() unit test so that we can detect any problems in our replacement function; add a new test function to make sure that gmtime<->timegm are a round-trip on now-ish times. This is a fix for bug #40383, wherein we ran into trouble because tor_timegm() does not believe that time_t should include a count of leap seconds, but FreeBSD's gmtime believes that it should. This disagreement meant that for a certain amount of time each day, instead of calculating the most recent midnight, our voting-schedule functions would calculate the second-most-recent midnight, and lead to an assertion failure. I am calling this a bugfix on 0.2.0.3-alpha when we first started calculating our voting schedule in this way.

o Minor bugfixes (timekeeping):
|
|
- Calculate the time of day correctly on systems where the time_t
|
|
type includes leap seconds. (This is not the case on most
|
|
operating systems, but on those where it occurs, our tor_timegm
|
|
function did not correctly invert the system's gmtime function,
|
|
which could result in assertion failures when calculating
|
|
voting schedules.) Fixes bug 40383; bugfix on 0.2.0.3-alpha.
