Hi

This is a very useful library, plain and simple.

I just want to point out an issue I stumbled upon.

The timezone passed in the constructor is required to be the timezone of the host. I had the issue because I test successfully on my local machine (in EUROPE/Brussels), but when deploying on docker container it failed.

The reason is that a docker container by default uses UTC. And having configured a timezone, the Next firing time is off by 2hours. (CEST vs UTC).

My expectation was that it would just execute all calculations based on the timezone. It would then be possible to expect a trigger every day at 14:00 in EUROPE/Brussels, while running on a UTC host.

Thanks for the effort, hope this helps.
