Cast from string to Datetimeoffset

HI,

I have a string date time which I am trying to convert into Datetimeoffset by (DT_DBTIMESTAMPOFFSET,6)(StringDate). But timezone ie(+5:30) is not displaying. But when I caste DATE datatype value then the value is displaying fine.(DT_DBTIMESTAMPOFFSET,6)(DATEDate).

Any suggestion for converting string to datetimeoffset so that offset(timezone) also displays.

Thanks in Advance.
