The below Parliamentary question was asked by Lord Tanlaw on 2016-09-05.

To ask Her Majesty’s Government whether they plan to review the use of British Summer Time, and what assessment they have made of the possible impact of maintaining BST throughout the year.

Baroness Neville-Rolfe

The Government has no plans to review the use of British Summer Time.

In 2012, the Government published a review of the available evidence concerning the likely effects of moving to Central European Time (also known as Daylight Saving time) in the UK. This is attached, but is also available on the Government website at the following link.

The below Parliamentary question was asked by Lord Tanlaw on 2016-09-05.

To ask Her Majesty’s Government whether they plan to change the meaning of the acronym GMT from Greenwich Mean Time to Greenwich Meridian Time.

Baroness Neville-Rolfe

We consider that any attempt to change the meaning of the acronym GMT is likely to result in confusion.

The below Parliamentary question was asked by Lord Tanlaw on 2016-09-05.

To ask Her Majesty’s Government whether they plan to identify accurately the GPS Prime Meridian with a corresponding marker at the correct location in Greenwich Park.

Baroness Neville-Rolfe

As the reference frame for the Global Positioning System (GPS) is established through a mathematical interpretation of satellite radio signals, rather than a physical meridian, it is not conceptually appropriate to represent it in the same way as other meridians have historically been marked at Greenwich.

The below Parliamentary question was asked by Lord Tanlaw on 2015-10-19.

To ask Her Majesty’s Government what assessment they have made of whether the prime meridian can be correctly identified and correlated with GPS by the construction (with permission) in Greenwich Park of a suitable marker located at zero longitude.

Baroness Neville-Rolfe

As the reference frame for the Global Positioning System (GPS) is established through a mathematical interpretation of satellite radio signals, rather than a physical meridian, it is not conceptually appropriate to represent it in the same way as other meridians have historically been marked at Greenwich.

We do not see any practical benefit in changing the reference point for UT1 even if it was a decision the UK Government could make unilaterally. Such a change could cause confusion as could use of the term “Greenwich Meridian Time”. In line with the International Telecommunication Union Radio Regulations, all time‑signal broadcasts in the UK transmit. the international timescale UTC, and so any change to UT1 or GMT would have no impact on the time-signal available to the UK public.

The below Parliamentary question was asked by Lord Tanlaw on 2015-10-19.

To ask Her Majesty’s Government what assessment they have made of the case for the civil timescale Greenwich Mean Time being renamed Greenwich Meridian Time, with a value of UT1 at longitude zero based on GPS rather than the historic location of the prime meridian.
