Who is widely known as the inventor of the system of World Wide Standard Time with time zones?

Introduction / Context:
Before standard time zones were adopted, local time was set mainly by the position of the sun, which caused confusion for railways and telegraph systems. The idea of World Wide Standard Time with coordinated time zones simplified travel, communication and scheduling. This question asks who is widely known as the inventor and strong promoter of that standard time system.

Given Data / Assumptions:

• The focus is on standard time and time zones on a global scale.
• The inventor proposed dividing the world into zones with defined offsets from a reference meridian.
• The options list names from different scientific and technical fields.
• We assume basic awareness that railways and telegraphs drove the need for standard time.

Concept / Approach:
Sandford Fleming, a Canadian engineer, is credited with advocating a worldwide system of time zones based on a standard prime meridian. His proposals influenced international conferences and led to the adoption of standard time. Other names in the options do not have the same clear connection to the creation of World Wide Standard Time, so we focus on Fleming.

Step-by-Step Solution:
Step 1: Identify that the concept of World Wide Standard Time is mainly an engineering and railway related reform, not a purely astronomical discovery. Step 2: Recall that Sandford Fleming proposed dividing the globe into twenty four time zones and promoted uniform standard time. Step 3: Connect Fleming with international discussions that later resulted in commonly used time zones. Step 4: Therefore, the person widely known as the inventor of World Wide Standard Time is Sandford Fleming.

Verification / Alternative check:
A quick check is to link Fleming name with railways and time zones. Many general knowledge sources describe him as the father of standard time. Other scientists such as mathematicians or inventors of telephone systems do not usually appear in that context. This repeated association confirms that Sandford Fleming is the correct answer.

Why Other Options Are Wrong:

• Friedrich Gauss: A mathematician noted for contributions to number theory and magnetism, not for standard time zones.
• Williamson: No well known direct association with the invention of World Wide Standard Time.
• James Broot: Not recognised in common historical accounts of standard time systems.
• Alexander Graham Bell: Famous for the invention of the telephone, not for designing the global standard time system.

Common Pitfalls:
Students sometimes misattribute the invention of standard time to astronomers or to any famous inventor from the nineteenth century. Another pitfall is to assume that whoever invented the telegraph or telephone must have also designed the time system used by those networks. To avoid such confusion, remember specifically that Sandford Fleming was an engineer deeply involved with railways and timekeeping, which makes him the key figure behind World Wide Standard Time.

Final Answer:
Sandford Fleming is widely known as the inventor and main promoter of World Wide Standard Time with time zones.
