Timer 的别名

call_after(*args: Any, **kwargs: Any) → Entry

call_at(*args: Any, **kwargs: Any) → Entry

call_repeatedly(*args: Any, **kwargs: Any) → Entry

cancel(tref: Entry) → None

clear() → None

empty() → bool

ensure_started() → None

enter(entry: Entry, eta: float, priority: int | None = None) → Entry

enter_after(*args: Any, **kwargs: Any) → Entry

exit_after(secs: float, priority: int = 10) → None

next() → float | None

on_tick: Callable[[float], None] | None = None

property queue: list

run() → None

Method representing the thread's activity.

You may override this method in a subclass. The standard run() method invokes the callable object passed to the object's constructor as the target argument, if any, with sequential and keyword arguments taken from the args and kwargs arguments, respectively.

running: bool = False

stop() → None

celery.utils.timer2.to_timestamp(d, default_timezone=zoneinfo.ZoneInfo(key='UTC'), time=<built-in function monotonic>)

Convert datetime to timestamp.

If d' is already a timestamp, then that will be used.
