Please can you suggest how to display time for ETA. It should display current time and future time with 30 minutes interval. it should not display previouse time. for example if date is today date and time is 13.30 , it should show time at drop down like 14.00, 14.30 etc. it should not display before time like 13.00 12.30. if we chose next day it should display time like 00.00 to 11.30, all slots for 24 hours.

You could achieve this by adding a non persistent entity, called ETA, with one attribute called Time and by datasource, create a list of these entities, with the Time set ascending per half hour based on the current time. Use a reference selector to select either one of these times from a drop down on your page.
Search the appstore for countdown, this might provide a simple solution.
