The most common way to figure out a time zone is by using the IANA Time Zone Database.
Then, the clock is reset to the time zone time in winter. DST or summer time adds one hour to the time zone offset before summer. In addition of this offset, which comes with the time zone, some countries also shift clocks twice a year. Yet, the shift isn’t only in whole hours: Nepal's offset is +0545. You may also heard about GMT which is a time zone without any offset.įor instance, when it’s 10:50 at UTC, it’s also 03:50 in San Francisco with a -0700 offset and 18:50 in Beijing with a +0800 offset. Global time is called UTC, it stands for Coordinated Universal Time. Standard world time zones - Illustration by Hellerick from Wikimedia Commons This offset is a number of minutes to add to the global time to get your time zone time. As a result, the globe gets split into time zones and each gets an offset. To make sure the time is coordinated with the sun for everyone, it’s necessary to shift from global time according to your location. If everyone used global time, let’s say 09:00 would be sunrise in Japan, but for Americans it would be sunset. Quick introduction to time zonesĪs the earth is kind of a sphere, the sun is rising in Japan while it's setting in America. In this article, I’ll introduce time zone issues and share some rules to follow.

This was an opportunity for me to learn how to correctly handle dates and times for international software. Here is the unit test working in France but not in Morocco There were some unit tests making assertions about dates that used to work at my office in France but weren't working in Morocco for new members on our team. I recently came across an issue involving timezones. Unless you live in a country which has to deal with multiple time zones, such as the United States or Russia. When you develop some software you may not think about timezones at first.
