I am getting
invalid date format 2011 when I try to the modified time, this works fine without the seconds
touch -t 2011 08 23 14 05 14 voucher.tpl
I am a little confused with the below that explains how to do this:
-t time specifies a particular time using this format:
where cc is the optional first 2 digits of the year, yy is the optional last 2 digits of the year, MM is the optional number of the month (01-12), dd is the optional day of the month, hh is the hour in 24 hour format (required), mm is the minutes (required), ss is the optional seconds.
