=item $dname |
|
|
|
The name to prepend to the form elements. |
|
The form elements defined will be dname_year, dname_month, dname_day, |
|
dname_hour, dname_min, and dname_sec. |

|
|
=item $currentvalue |
|
|
|
The current setting for this time parameter. A unix format time |
|

Also, to be explicit, a value of 'now' also indicates the current time. |
|
|
|
=item $special |
|
|
|
Additional html/javascript to be associated with each element in |
|
the date_setter. See lonparmset for example usage. |
