Computer is a dumpbox. it only understands the configurations made by administrator. If you set the date to some other date then that will reflect there.

No. You can use SNTP to get the real date and time (see this[^] and this[^]) with an internet connection. If you have a network connection that the computer can use where a computer exists that does have an internet connection, then you can use that as an SNTP server for the client. Otherwise, you are stuck with the System's date/time.

Hi,

The computer know which we set on it,(if we set some date for it, then it show the same); but if it didn't know the date then how can It produce date for you for any programming language.
eg. If I put you in a dark room for several days without any gadget/communication(clock) then Can you identify what is real time or date, same for computer(if you Initialize wrong clock to computer then it return you wrong time)

you cant get real date without setting on your computer.

So If you can create your clock then you can set it first time with real date and you will returned always real date time.

Thank You.
Please mark as ans. if it helps you.
