You're on a plane heading somewhere, you cross several time zones, and you will possibly suffer from jet lag later because your inner clock rebels.
Earth is divided into 24 segments known as lunes.
Standard US Time-Zones (click map to enlarge)
A time zone is defined as an area where a uniform standard time applies for legal, economic and social purposes. Standard time zones are 15 degrees of longitude wide.
A time zone is ideally one of 24 spherical lunes (a section on the globe in a north/south direction) with equal-width (15 degrees), each assigned with one of the 24 hours (makes together one day and one rotation of the Earth).
Normally, a uniform standard time is maintained in each section to track the day and night cycle. This means that people in each geographic region within a time zone use the same time.
All these zones are defined by an offset from the Coordinated Universal Time (UTC; see below) by a number of hours (UTC−12 to UTC+14) centered on the prime meridian (0°; since 1884 the Greenwich meridian [1]).
Today's use of time zones tends to follow more often the boundaries of countries and their subdivisions instead of the standard parallels because it is convenient in close economic or political areas to keep the same time. For example, most of Alaska uses Alaska Time, which spans three standard time zones. The state used two time zones until 1983, when it placed the capital, Juneau, in the same time zone as the more populous Anchorage and Fairbanks.
China spans four time zones but uses only one. The time difference between Bangkok, Thailand, and Kuala Lumpur, Malaysia, is one hour, although the two capitals are on almost the same longitude.
U.S. Time Zones
The time zone map below shows the six time zones of the United States, and a series of clocks show the actual time in the different time zones.
U.S. Daylight Saving Time
In the United States, Daylight Saving Time begins at 2 a.m. on the second Sunday in March and ends at 2 a.m. on the first Sunday in November. Two states don't observe daylight saving time, Arizona and Hawaii.

read moreAs time went by, this blog was developed for many different purposes. Last time, I had a lot of pleasure in sharing some of my Lego-related hobbies. However, I will mostly upload a blog about bikes and their development in the next few months! Recently, I have so much into ebike cargo. They say this type of bike can replace the car! And I am very into it since my place is crowded with traffic jams! The video above showed a funny situation: I started the review from Brooks's handle! And after nine years! It's still an excellent bike handle and not even destroyed!

Hi, hi, hi. So, it's been a while for the last couple of weeks since I have considered buying a cargo bike. The reason is that I am often trapped in a traffic jam because I can't get faster in my car.

Custom LEGO Transformers Devastator
My faith in humanity is restored! OK, that’s a bit overboard – but you couldn’t blame me if you see an incredibly, exquisitely and wonderfully executed custom LEGO Transformers Devastator such as this by Alex Jones. I feel transported to the 80’s once again, with the same intense childhood wonder when I first saw the Constructicons combine and become the formidable Devastator.
