1. What is Time Duration Calculation?

Time duration calculation measures the elapsed time between two points in time. It's a fundamental calculation used in various fields including physics, computing, and project management.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Start Time} \) — The beginning time point in seconds
• \( \text{End Time} \) — The ending time point in seconds

Explanation: The calculation simply subtracts the start time from the end time to determine the elapsed duration.

3. Importance of Time Duration Calculation

Details: Accurate time duration measurement is essential for performance analysis, process optimization, scientific experiments, and many timing-related applications.

4. Using the Calculator

Tips: Enter both times in seconds (can be decimal values). The end time must be greater than the start time for a valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for hours or minutes?
A: Yes, but you need to convert to seconds first (1 hour = 3600 seconds, 1 minute = 60 seconds).

Q2: What's the maximum duration this can calculate?
A: There's no practical limit as long as your numbers are within PHP's floating-point range.

Q3: How precise is the calculation?
A: The calculator supports decimal seconds for millisecond-level precision.

Q4: Can I calculate negative durations?
A: No, the calculator only works when end time is greater than start time.

Q5: What if my times are in different formats?
A: Convert all times to seconds before using this calculator for consistent results.
