Disable the past time slots from nb-date-timepicker

[ChirappaVishnupriya]

I am using nb-date-timepicker with singlecolumn below is the snippet

<nb-date-timepicker #dateTimePicker singleColumn [step]="5" [min]="minDate" [max]="maxDate">

min input is disabling the date only i have added time stamp also its not disbaling the time slots taht mention in the minDate.From above screenshot you can see for example Time is 11:25 it should start from 11:25 or past times able to diable.

Please consider this and provide me any solution for it .It woulb be great if you suggest any other option also

Thanks in advance
