Daylight Saving Time vs. World Time Zone Map: Is there a Difference

People often get confused when it comes to keeping time, which is quite understandable given that there are so many ‘standards’ to choose from. There’s the local time, the Coordinated Universal Time (UTC), and the time offset Daylight Saving Time (DST). Though each of these can help you tell time, only the UTC standard is the one being imposed to give uniform time across the world time zone map.


World Time vs. Local Time


Technically speaking, the local time is defined by its difference relative to the UTC. For example, if you live in Taiwan, you’ll have a time zone of UTC+8. This means that the whole country is 8 hours ahead from the standard time (which is why when it is Monday morning in Taiwan, it is only late Sunday evening in the US). Consequently, if you live in a region with time zone UTC-8 then that means that you are 8 hours behind the standard time. offers some in-depth insights on world time zone map.

However, not all countries adapt the whole number scheme. Some uses 30- or 45-minute offset. For example, the Northern Territory of Australia uses UTC+9:30, Southern Australia uses UTC+10:30, and Central Western Australia uses UTC+8:45. This is because Australia uses both vertical and horizontal time zones during summer time, which can often lead to confusion. Moreover, some regions use DST while other regions don’t, which adds to the confusion.


Time Offset


Time offset or DST is often used by regions to help maximize the sun’s available light particularly during the changing of seasons. However, not all regions follow DST.


Take for instance, the State of Arizona in the US. Unlike the majority of the country, Arizona does not apply DST simply because they have been experiencing intense heat during daytime. For this reason, most of its residents have already adjusted their own body clocks to work much later when it is cooler. Thus, Arizona follows the standard time all year-round.
