Nowadays, Greenwich Mean Time, abbreviated as GMT, is a time zone designation rather than a time standard. Time difference between time zones can be expressed by the GMT or UTC hour difference. In the UTC standard, there is a commitment to keep within 0.9 seconds of GMT, so that every few years a leap second is applied to UTC. In the age of the internet, these small clock calibrations are conveniently distributed via NTP.
GMT+3 is 3 hours ahead of Greenwich Mean Time (GMT).
