Since weather maps and charts often display the time in UTC (coordinated universal time) or "zulu" time, this chart will allow you to convert UTC / zulu time to your local time. On weather charts, UTC time is often abbreviated or written in several ways, for example 12 noon UTC time may be written 1200Z or sometimes simply 12Z. Note that since some provinces change back and forth between daylight savings time, there are both summer and winter conversion charts.
