Date constructor New Date () | Date ()

If no parameter is specified, the default time is the current time zone of the system. The result is as follows:

Sat Apr11 2015 16:42:09 GMT + 0800 (China Standard Time)

Generation represents the time of the current system, which can be generated without the use of new. Date itself is a method.

New Date (milliseconds)

This millisecond parameter is the time that has elapsed since 00:00:00.

New Date (datestring)

ECMA is not specified, so only the supported formats are listed.

ISO format time

The most significant feature of ISO format time is the separation of hyphens (-) between years, months, and days. The date and time may have a letter (T), followed by a letter Z or time difference.

T is meaningless. It only indicates that the date and time are separated here; Z indicates that the time is UTC time.

Rule Summary:

• The date and time string with the time zone indicates the time of the specified time zone. The date and time string without the time zone is divided into two situations: the date and time string of the ISO-like structure represents the current time zone of the system, the date and time string of the ISO standard structure represents the current time of the Greenwich Meridian.
• Z or z not only indicates UTC time, Z also indicates that this date and time string represents the time of 0 time difference offset, as in Greenwich Mean. However, the time difference can be added after Z, and the offset is calculated from 0.
• Because Date is generated on the client, the actual Date has been converted to the time of the local system. Note that after the Date and time string is changed to the Date object, the value of time and date may be different from the value in the string.
