Since June 2001, the Lithuanian National Time and Frequency Standard Laboratory has been responsible for the maintenance and dissemination of the national time scale UTC (LT), as well as for units of time and frequency. The Laboratory is equipped with two HP5071A atomic clocks (one with a high-performance Cs tube) and two multi-channel TTS-1 and TTS-2 GPS receivers. The TTS-2 system is fitted with a temperature-stabilized GPS antenna. For dissemination of the Lithuanian Time Scale UTC (LT), the Datum 2001 and SyncServer S250 NTP servers are used. Laboratory activities on coordination of the BALTICTIME project Reinforcing e-Government services in Baltic States through legal and accountable Digital Time Stamps (a European FP6 program) are presented. Also, the applications in legal metrology of the technology developed for measuring GSM audio call durations by generating digital time marks traceable to UTC (LT) are demonstrated.
