           Product: WebKit

          Platform: All

Creating date's prior to 1 Mar 1000 will create a date object a day too early.

Here's example code:


// Correct dates
new Date("1 Jan 1900"); // Mon Jan 01 1900 00:00:00 GMT+0000 (GMT)
new Date("1 Jan 1500"); // Mon Jan 01 1500 00:00:00 GMT+0000 (GMT)
new Date("1 Jan 1001"); // Thu Jan 01 1001 00:00:00 GMT+0000 (GMT)
new Date("1 Mar 1000"); // Sat Mar 01 1000 00:00:00 GMT+0000 (GMT)

// In correct dates
new Date("28 Feb 1000"); // Thu Feb 27 1000 00:00:00 GMT+0000 (GMT)
new Date("1 Dec 988"); // Sun Nov 30 0988 00:00:00 GMT+0000 (GMT)
