    Getting a GMT_UNIX_time structure in Windows

    I need to get the system time from a Windows machine in a certain format, namely the GMT_UNIX_time format which is the number of seconds elapsed from the midnight starting Jan 1st 1970. Does anyone know how to do that?

    time
    The encoding of the return value is unspecified, but it may be in seconds since ...

    I don't understand your reply, none of the first 10 links on that google search relate to a time function.

    He wants you to use the UNIX man pages. Try searching for "unix man time" instead.

    But, I need this to work under Windows, so how would a UNIX shell command help me?

    man pages are help files.

    Right, I know what a man page is, I've used linux/unix/bsd before. What I need is a C++ function of some sort to get a time structure in Windows, so a unix man page doesn't help me.

    Look... we could go on this forever, but obviously you are not making one ounce of an effort.

    google "man unix time". You will get a list of links that will help you with the time function.

    Then, when you actually click the links on google you will know why people are sending you there. It's an help file!

    Unless there is something wrong with the structure that the time.h functions return, I really don't see your point. I'm confident that the man page will help you understand if you would just read it.

    time.h is standard so it is cross-platform. It's irrelevant what documentation you read as long as it is from a reliable source.

    Then look up the time function in your compiler's documentation. Can you be more thick?

    He's being sent to the time command, citizen. Which is fine. However, obviously it didn't even cross his mind to just perhaps type on google "man page time c++" or "c++ time help" or "how to use time c++" or... "duh!"
