I am developing a custom module where there are many fields text,select,multiselect..etc in admin form.

Today I have added one field in admin of type time ,below is the code to add new field

$timeFormat = $this->_localeDate->getTimeFormat(\IntlDateFormatter::MEDIUM);

$actionTime = $fieldset->addField(
                        'name'      => 'action_time',
                        'label'     => __('Time'),
                        'class'     => 'required-entry',
                        'required'  => true,
                        'time_format'=> $timeFormat,

and in installSchema.php I have put below code to add column in table

            ['nullable' => false],
            'Action Time'

Field created successfully but it throwing error when saving form. enter image description here

I have debugged but not found any issue.Please help me.

  • it could be an issue with the time format, test it with static format like 'time_format' => 'hh:mm:ss' or 'time_format' => 'H:i:s', – fmsthird Apr 25 at 10:09
