| Help: Transfer based on a time condition |
| Request a file that has been modified later than the given time and date, or |
| one that has been modified before that time. The <date expression> can be all |
| sorts of date strings or if it doesn't match any internal ones, it is taken as |
| a filename and tries to get the modification date (mtime) from <file> |
| instead. See the *curl_getdate(3)* man pages for date expression details. |
| Start the date expression with a dash (-) to make it request for a document |
| that is older than the given date/time, default is a document that is newer |
| than the specified date/time. |
| If this option is used several times, the last one will be used. |
