The functions for attributes with datatype Date require a long value as time stamp, in the UNIX Epoch time format 1234567890000, and a string value as calendar date, in the ISO extended format YYYY-MM-DD.
Warning Using negation (!) at the beginning of any function can cause unexpected validation results.
