Invoked periodically
If you want to control at what to invoke this function next time
you can set the value of the global variable `wait_period` to the
number of seconds to wait before invoking this function again.
The value does not need to be an integer.
@param year:int The year
@param month:int The month, 1 = January, 12 = December
@param day:int The day, minimum value is 1, probable maximum value is 31 (*)
@param hour:int The hour, minimum value is 0, maximum value is 23
@param minute:int The minute, minimum value is 0, maximum value is 59
@param second:int The second, minimum value is 0, probable maximum value is 60 (**)
@param weekday:int The weekday, 1 = Monday, 7 = Sunday
@param fade:float? Blueshift can use this function to fade into a state when it start
or exits. `fade` can either be negative, zero or positive or `None`,
but the magnitude of value cannot exceed 1. When Blueshift starts,
the this function will be invoked multiple with the time parameters
of the time it is invoked and each time `fade` will increase towards
1, starting at 0, when the value is 1, the settings should be applied
to 100 %. After this this function will be invoked once again with
`fade` being `None`. When Blueshift exits the same behaviour is used
except, `fade` decrease towards -1 but start slightly below 0, when
-1 is reached all settings should be normal. Then Blueshift will NOT
invoke this function with `fade` being `None`, instead it will by
itself revert all settings and quit.
(*) Can be exceeded if the calendar system is changed, like in 1712-(02)Feb-30
