How "not to change" file attributes when editing via ruby?

I use ruby -pi~ -e \"gsub(/\\\"/, \\\"'\\\")\" \"#{dir}\\*.csv\" to replace double quotes by single quote in all files in a directory #{dir}

It works well but it changes the date/time of the file to current one.

How can I preserve the time/date properties of the file(s)?

You can't but you can set the modification time back to before the change like this

original_time= File.mtime('myfile')
p original_time

date = Time.now - 86400
File.utime(date, date, 'myfile')
p File.mtime('myfile')

File.utime(original_time, original_time, 'myfile')
p File.mtime('myfile')

#2012-10-04 02:28:25 +0200
#2012-10-03 02:28:25 +0200
#2012-10-04 02:28:25 +0200

utime(atime, mtime, file_name,...) → integer click to toggle source Sets the access and modification times of each named file to the first two arguments. Returns the number of file names in the argument list.
