As the United Kingdom grew into an advanced maritime nation, British mariners kept at least one chronometer on GMT in order to calculate their longitude from the Greenwich meridian, which was by convention considered to have longitude zero degrees. Most time zones were based upon this reference as a number of hours and half-hours "ahead of GMT" or "behind GMT".
