I recently switched from OP to NP.I am a marine engineer and I am presently at sea sailing..we have frequent time advances and retards as we keep moving from one place to another,normally as we advance/retard clocks i set my phone using the GMT time mentioned under different countries in Time zones but in NP,GMT details are not mentioned in the list have to check manually.Also compared to OP,NP has lesser countries and timezones selections.Can anything be done for chaps like me or who are travelling across the globe frequently using the timezone functions.
