Re: ctime: creation or change time?

I understand that you're trying to be POSIX-like, but I wonder if doing
so at the cost of compatibility with the host OS is wise.  To be sure,
the implementation you have chosen will break some Windows
applications.

It seems to me that ultimately you are emulating POSIX-like behavior on
top of what is fundamentally NOT a POSIX-like system.  If that is so,
then why not use a different implementation that is sure not to break
existing non-Cygwin Windows applications?  The proposal I made
previously (report Windows modify time as both Cygwin mtime and ctime)
would give Cygwin applications a reasonable approximation of ctime in
the POSIX sense, while retaining a correct value of creation time for
Windows applications.


Your arguments would be a little more persuasive if you did more than
postulate the surety of breakage and actually pointed to real breakage
or, at least, demonstrated how a windows application would be harmed by
cygwin's handling of ctime.

The problem described in the following post to this mailing list earlier today sounds like it is caused by Cygwin's new treatment of ctime:
