dav date
========

**`date [url]`**

The purpose of this command is to get the current date from a server and print it to stdout (HTTP date format). This in useful in combination with the `-U` option for the `list` and `get` command.

The *url* can be any http url. If no *url* is specified, the local time is used.

### Example: incremental dav get

It is possible to download only resources, which are modified since a specified date. The *date* command allows you to easily store the date of the last *get*.

	$ dav get -R myserv/col/
	...
	$ dav date myserv > last_get
	
After some resources are changed on the server, you can download only the modified files.

	$ dav get -R -U `cat last_get` myserv/col/
