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. ---*/ const minDateStr = "-271821-04-20T00:00:00.000Z"; const minDate = new Date(-8640000000000000); assert.sameValue(minDate.toISOString(), minDateStr, "minDateStr"); assert.sameValue(Date.parse(minDateStr), minDate.valueOf(), "parse minDateStr"); const maxDateStr = "+275760-09-13T00:00:00.000Z"; const maxDate = new Date(8640000000000000); assert.sameValue(maxDate.toISOString(), maxDateStr, "maxDateStr"); assert.sameValue(Date.parse(maxDateStr), maxDate.valueOf(), "parse maxDateStr"); const belowRange = "-271821-04-19T23:59:59.999Z"; const aboveRange = "+275760-09-13T00:00:00.001Z"; assert.sameValue(Date.parse(belowRange), NaN, "parse below minimum time value"); assert.sameValue(Date.parse(aboveRange), NaN, "parse above maximum time value"); reportCompare(0, 0);
