>From "man touch" on Solaris 10:
A user with write access to a file, but who is not the owner
of the file or a super-user, can change the modification and
access times of that file only to the current time. Attempts
to set a specific time with touch will result in an error.
I.e., if you don't own a file, following works in Solaris:
$ touch thefile # sets current time -> ok
But the following doesn't:
$ touch -t 200909111155 thefile # sets a given time -> not ok
So, I'd expect ant's touch task, without datetime argument, to also work in
this case. However it doesn't. Also, it doesn't signal an error about the
failure to set the modification time.
Looking into the source code, I found that ultimately, the touch task (without
datetime argument) calls thefile.setLastModified(System.currentTimeMillis()).
This is probably equivalent to calling touch with a given datetime argument
(namely the current time), which doesn't work.
