Hi! Thanks a lot for your answers!! I played around a bit and figured out, that the timestamp is updated if the file is not empty. If the file is empty the timestamp is NOT updated: Client: apfel:~ ts$ echo "abc" > test apfel:~ ts$ touch test apfel:~ ts$ ls -l test -rw-r--r-- 1 ts staff 4 23 Jul 15:54 test apfel:~ ts$ curl -T test -u zotero:secret http://abc.de/zotero/test (...waiting for 2 minutes...) apfel:~ ts$ touch test apfel:~ ts$ ls -l test -rw-r--r-- 1 ts staff 4 23 Jul 15:56 test apfel:~ ts$ curl -T test -u zotero:secret http://abc.de/zotero/test Server: root@abc:/etc/apache2# ls -l /var/zotero/test -rw-r--r-- 1 www-data www-data 4 2010-07-23 15:54 test root@abc:/etc/apache2# ls -l /var/zotero/test -rw-r--r-- 1 www-data www-data 4 2010-07-23 15:56 test However, it does _not_ work if the file is empty: Client: apfel:~ ts$ touch empty apfel:~ ts$ ls -l empty -rw-r--r-- 1 ts staff 0 23 Jul 16:03 empty apfel:~ ts$ curl -T empty -u zotero:secret http://abc.de/zotero/empty (...waiting for 2 minutes...) apfel:~ ts$ touch empty apfel:~ ts$ ls -l empty -rw-r--r-- 1 ts staff 0 23 Jul 16:05 empty apfel:~ ts$ curl -T empty -u zotero:secret http://abc.de/zotero/empty Server: root@abc:/etc/apache2# ls -l /var/zotero/empty -rw-r--r-- 1 www-data www-data 0 2010-07-23 16:01 /var/zotero/empty root@abc:/etc/apache2# ls -l /var/zotero/empty -rw-r--r-- 1 www-data www-data 0 2010-07-23 16:01 /var/zotero/empty I need to use a sync software, that stores the date and time of the last sync in an empty file called "lastsync". My problem ist that the timestamp of this file is not updated properly. THX again!
