Answer 1

嗨我认为找到了一个解决方案，它有一些延迟Mr.c解释。

def run(self):
    while True:
        time.sleep(10-time.time()%10) #sleep to the start of next min
        print time.time()

这是一个10秒的模拟..

Answer 2

考虑使用sched Python模块。你说＆＃34;在确切的时间运行X＆＃34;或者＆＃34;在Y秒过后运行。＆＃34;它是标准的，支持多线程。

fine documentation:

中的示例

>>> import sched, time
>>> s = sched.scheduler(time.time, time.sleep)
>>> def print_time(): print "From print_time", time.time()
...
>>> def print_some_times():
...     print time.time()
...     s.enter(5, 1, print_time, ())
...     s.enter(10, 1, print_time, ())
...     s.run()
...     print time.time()
...
>>> print_some_times()
930343690.257
From print_time 930343695.274
From print_time 930343700.273
930343700.276
