好似寫(xiě)的有點(diǎn)復(fù)雜。把倒計(jì)時(shí)時(shí)間，重置時(shí)間，計(jì)時(shí)器的偏差都加上了。
var s = 1000,
m = 60 * s,
h = 60 * m,
d = 24 * h,
tick_time = 1000,
timezone = new Date().getTimezoneOffset() * m;
var getDayTime = function(t) {
t = t.split(':');
return t[0] * h + t[1] * m;
}
var getNextClock = function(clockTime, resetTime, now) {
var result = now_d = parseInt(now / d, 10) * d + timezone;
now_d_t = now - now_d;
if (now_d_t > resetTime) {
result += d;
}
return result + clockTime;
};
var before = 0,
resetTime = getDayTime('00:00'),

var tickHandler = function() {

console.log(diif_readable);

var handler = setInterval(tickHandler, tick_time/10);
tickHandler();
