Check the stat man page
man 2 stat
That will get modified and access times, mode, size, etc,

You can get the time in seconds with time(0)

Unless you're thinking of something like a locally mounted NFS volume,
this can be very complicated. You can check up on various URL libraries.

You should read various RFC (http://www.rfc-editor.org/)
Search for NFS, FTP, HTTP, WebDAV, and perhaps others that I don't
remember right now. There, you'll have all the specifications needed
to implement the protocols needed to access a remote file through a C
program.

the "stat" or "lstat" system calls can get you the informatiion you need

the "time" function can give you the system time (in seconds elapsed
since the great beginning)
