+ This module performs a read-only limitation for specified share
+ (or all of them if it is loaded in a [global] section) based on period
+ definition in smb.conf. You can stack this module multiple times under
+ different names to get multiple limit intervals.
+
+ The module uses get_date() function from coreutils' date utility to parse
+ specified dates according to date(1) rules. Look into info page for date(1)
+ to understand the syntax.
+
+ The module accepts one parameter:
+
+ readonly: period = "begin date","end date"
+
+ where "begin date" and "end date" are mandatory and should comply with date(1)
+ syntax for date strings.
+
+ Example:
+
+ readonly: period = "today 14:00","today 15:00"
+
+ Default:
+
+ readonly: period = "today 0:0:0","tomorrow 0:0:0"
+
+ The default covers whole day thus making the share readonly
