Example of adding a parameter with a date interval
To set the date and time interval between 03-08-2018 09:00:00 and 10-08-2018 10:00:00, set the parameter to __interval_2018-08-03T09:00:00_2018-08-10T10:00:00.
Example of adding a parameter with a relative date
To set the date and time interval from the beginning of the last week of 2018 until today, set the parameter to __interval_2018-12-23___relative_+0d.

Note
Note: If no casting is specified, then for the units of one day and higher, the time is cast to the start of the day, that is, 00:00:00.000, while casting to the current time is used for smaller time units.
