How to get full time stamp value from flatpickr

Question

Current I can get the value like dateFormat: 'y-m-d' 22-03-18 , But i want full time stamp like that 2022-03-19T01:24:33.374355+01:00 The reason is that I'm getting timestamp from Django in this format and I want to filter out to get the range using flatpicker That's my current code :

           <Col lg="4" md="6" className="mb-1">
          <Label className="form-label" for="date">
            Date:
          </Label>
          <Flatpickr
            className="form-control"
            id="date"
            value={Picker}
            options={{ mode: 'range', dateFormat: 'y-m-d' }}
            onChange={(date) => handleDateFilter(date)}
          />
        </Col>

I have read the docs https://flatpickr.js.org/options/ as well but didn't able find the solution. So please if any one knows how to get to fix that ??
