I'm using Signup with Date 6.x-2.7 and an optional CCK-Field for the date. Besides I have set the variable signup_close_early in the module settings to an empty value, because I don't want any autoclosing.

Now after each cron run I keep getting a PHP-Error in my dblog:

date_modify() [function.date-modify]: Failed to parse time string (+ hours) at position 0 (+): Unexpected character in (...)/sites/all/modules/signup/includes/date.inc in Zeile 362.

After reading the code it seems that the variable signup_close_early is treated as a mandatory input. Shouldn't there be a validation of this setting if it is mandatory?

Besides how am I supposed to disable autoclose completely?
