1. What is Time Subtraction?

Time subtraction calculates the difference between two time values expressed in hours, minutes, and seconds. This is useful in various fields like physics, sports timing, and work hour calculations.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Diff seconds} = \text{Total seconds1} - \text{Total seconds2} \]

Where:

Explanation: The calculator first converts both time values to total seconds, subtracts them, and then converts the result back to HMS format.

3. Importance of Time Calculation

Details: Accurate time difference calculation is essential for scheduling, time tracking, scientific experiments, and many other applications where precise time measurement is required.

4. Using the Calculator

Tips: Enter hours, minutes, and seconds for both time values. The calculator will display the difference in both HMS format and total seconds.

5. Frequently Asked Questions (FAQ)

Q1: What if the result is negative?
A: A negative result means Time 2 is greater than Time 1. The calculator shows the absolute difference with a minus sign.

Q2: Can I input values greater than 59 for minutes/seconds?
A: The calculator restricts minutes and seconds to 0-59, as these are standard time units.

Q3: How precise is the calculation?
A: The calculation is exact, with no rounding until the final display of results.

Q4: What's the maximum time difference that can be calculated?
A: The calculator can handle very large time differences, limited only by PHP's integer size.

Q5: Can this be used for date differences?
A: No, this calculator only handles time-of-day differences, not calendar date differences.
