+The name to prepend to the form elements.

+
+The current setting for this time parameter. A unix format time
+(time in seconds since the beginning of Jan 1st, 1970, GMT.
+An undefined value is taken to indicate the value is the current time.
+Also, to be explicit, a value of 'now' also indicates the current time.
