格林尼治报时信号(英语:The Greenwich Time Signal)是英国广播公司电台间隔1秒所发送的6个短音系列信号,该信号系统在1924年时首次发送,并且自1990年开始改由英国广播公司负责信号设置工作。信号的功能是为了能够精确标记每个小时,借由数字广播来作为确认时间是否有延后的校准工具。

Greenwich Time Signal 格林尼治报时信号
The Greenwich Time Signal (GTS), popularly known as the pips, is a series of six short tones broadcast at one-second intervals by many BBC Radio stations. The pips were introduced in 1924 and have been generated by the BBC since 1990 to mark the precise start of each hour. Their utility in calibration is diminishing as digital broadcasting entails time lags.
