The UK is recognised as world leading in time dissemination and the National Timing Centre programmeis establishing a national timing authority to enable better regional timing capability. Although two data bits are transmitted per second, the time code has the property that only one of them is variable; non-zero B bits are only transmitted when the corresponding A bit has a fixed value. Neutral 20%. Improved resilience will help to strengthen our societythrough faster, more secureinternet, robust energy supplies and reliable health and emergency services. .

Bits 17A51A encode the time of the following minute in binary-coded decimal, most significant bit first. [14] According to the NPL it seems the call sign was chosen so that it could be memorized as "Master Standard Frequency" but MSF was not intended to be an abbreviation. [6] The official history of the service says that "Rugby was given an additional commitment for the transmission of reference Modulated Standard Frequencies", but no actual explanation is given for the call sign "MSF". One of the key objectives of the National Timing Centre (NTC) programme is focused on responding to the specialist skills shortage in time, frequency and/or synchronisation (TFS).
