Hi Jayesh, 

Thanks for adding your request to the community! The requested "available_time" field field represents denormalized data. It can be calculated from underlying raw data, which is why we are not syncing them. You can find the reasoning behind this decision in our Shared Responsibility Model: https://fivetran.com/docs/getting-started/core-concepts#sharedresponsibilitymodel

That said, for this particular field, it's not immediately clear to me what the calculation formula to determine this value would be. If you know it, we will be interested to make sure that the underlying data points are available.

Best regards,

Ray Harris
