   The query can be passed for the whole date or for it's part:

   • FULL - current date as a whole: year, month, day of month formatted as YYYY-MM-DD (a default return value);
   • YEAR - current year;
   • MONTH - name of the current month;
   • DAY - current day of month; In any other case throw DateTimeException.

2. Given an Array of 3 elements, where - 1-st element is a year; - 2-nd element is s month; - 3-rd element is a day of month;

   Return Optional of a date built from these elements.

8. Given a String representation of a date and some timezone, return LocalDateTime in this timezone.

9. Given some LocalDateTime, return an OffsetDateTime with the local time offset applied (+02:00 for Ukraine).

   Example: we receive a LocalDateTime with a value 2019-09-06T13:17.
   We should return the OffsetDateTime with a value 2019-09-06T13:17+02:00,
   where +02:00 is the offset for our local timezone.

   OffsetDateTime is recommended to use for storing date values in a database.
