[Validation] Display correct validation message for TimeType fields

**Description**  
When using validations like GreatherThan, NotEqualTo, etc. (compare 2 TimeType fields) the current message output on TimeType fields will be "This value should not be 1970/01/01 00:00" instead of "This value should not be 00:00"

**Example**  
Validation output: 
"This value should not be 00:00"
"This value should be greather than 00:00"
