Thread:Project:Support desk/compressOld.php/reply

The script has the option -e, which defines the end date. Reading the source code, the script expects the value to be an integer with a length of 14 signs. This integer is then used to compare it against the value from rev_timestamp in your database. This means that you have to provide the date in the format, which is specified on Manual:Timestamp.

I have updated Manual:CompressOld.php to make that more clear.
