dav date
date [url]
The purpose of this command is to get the current date from a server and print it on 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/
