There was a problem hiding this comment.
These lines are duplicated in 2 places in this block of code, should they be extracted into a helper method?
if (params != null && params.length > 1) {
throw new IllegalArgumentException(
"Timestamp takes only one parameter, but " + params.length + " is seen");
}

The same exception error message is reused in TimestampTypeInfo constructor, should we define a common error message in ErrorMsg for reuse?
