Time Difference between UTC and PST Pacific Standard Time (North America) is 8 hours behind from the UTC universal time. UTC to PST Time Conversion Table UTC to PST in 12-hour (AM/PM) time format. Time Difference between UTC and CST Central Standard Time (North America) is 6 hours behind from the UTC universal time. UTC to CST Time Conversion Table UTC to CST in 12-hour (AM/PM) time format.
What is UTC or GMT Time?
Weather observations around the world (including surface, radar, and other observations) are always taken with respect to a standard time. By convention, the world's weather communities use a twenty four hour clock, similar to 'military' time based on the 0° longitude meridian, also known as the Greenwich meridian.
Prior to 1972, this time was called Greenwich Mean Time (GMT) but is now referred to as Coordinated Universal Time orUniversal Time Coordinated (UTC). It is a coordinated time scale, maintained by the Bureau International des Poids etMesures (BIPM). It is also known as 'Z time' or 'Zulu Time'.
To obtain your local time here in the United States, you need to subtract a certain number of hours from UTC dependingon how many time zones you are away from Greenwich (England). The table below shows the standard difference from UTC time to local time.
The switch to daylight saving time does not affect UTC. It refers to time on the zero or Greenwich meridian, which is notadjusted to reflect changes either to or from Daylight Saving Time.
However, you need to know what happens during daylight saving time in the United States. In short, the local time is advanced one hour during daylight saving time. As an example, the Eastern Time zone difference from UTC is -4 hours during daylight saving time rather than -5 hours as it is during standard time.
