+ Date.parse return value is limited to specified time value maximum range
+info: |
+ Date.parse ( string )
+
+ parse interprets the resulting String as a date and time; it returns a
+ Number, the UTC time value corresponding to the date and time.
+
+ A Date object contains a Number indicating a particular instant in time to
+ within a millisecond. Such a Number is called a time value.
+
+ The actual range of times supported by ECMAScript Date objects is slightly
+ smaller: exactly -100,000,000 days to 100,000,000 days measured relative to
+ midnight at the beginning of 01 January, 1970 UTC. This gives a range of
+ 8,640,000,000,000,000 milliseconds to either side of 01 January, 1970 UTC.
