## How to use
There are several ways to configure and use this library:

All of these examples will do the same things: print `Called` message every five seconds.
### do\* functions
With regular `doOnce`/`doWhile`/`doInfinity` there are two types of their variations: **local** and **timezoned**. Local
variations (`doOnceLocal`/`doWhileLocal`/`doInfinityLocal`) will pass `DateTime` as an argument into the block:
```kotlin
doInfinityLocal("/5 * * * *") {
println(it) // will print current date time
}
```
Timezoned variations (`doOnceTz`/`doWhileTz`/`doInfinityTz`) will do the same thing but pass as an argument `DateTimeTz`:
```kotlin
doInfinityTz("/5 * * * * 0o") {
println(it) // will print current date time in UTC
}
```
It is useful in cases when you need to get the time of calling and avoid extra calls to system time.
#### Helpful table for
| | No args | Local `DateTime` | Local `DateTimeTz` with offset of `KronScheduler` |
|---| ------- | ---------------- | ------------------------------------------------- |
| **Call only near time** | doOnce | doOnceLocal | doOnceTz |
| **Call while condition is true** | doWhile | doWhileLocal | doWhileTz |
| **Work infinity*** | doInfinity | doInfinityLocal | doInfinityTz |
*Here there is an important notice, that `Work infinity` is not exactly `infinity`. Actually, that means that `do while
coroutine is alive` and in fact executing will be stopped when coroutine became cancelled.
### KronScheduler as a Flow
Any `KronScheduler`can e converted to a `Flow<DateTime` using extension `asFlow`:

Offsets in this library works via passing parameter ending with `o` in any place after `month` config. Currently
there is only one format supported for offsets: minutes of offsets. To use time zones you will need to call `next`
method with `DateTimeTz` argument or `nextTimeZoned` method with any `KronScheduler` instance, but in case if this
scheduler is not instance of `KronSchedulerTz` it will works like you passed just `DateTime`.

Besides, in case you wish to use time zones explicitly, you will need to get `KronSchedulerTz`. It is possible by:
