Re: fixing crlf without changing timestamp

[michael sorens]

I'm not familiar with applying ant patches, plus I don't have a strong need for 
the fixcrlf right now, so I'm going to have to postpone any trials for the time 
being...

Is it possible to run <fixcrlf> without changing a file's
modification time? Or perhaps a way to use <touch> to restore the
original modification time after the <fixcrlf> (on a group of
files)?  I actually want to run fixcrlf in conjunction with copy
(which has the preservelastmodified attribute to retain the
modification time) but I see no way to do this.

The fixcrlf task doesn't support it yet. Could you try this patch?
