Formulas Used:

Total Duration in Milliseconds:

\( \Delta t = t_{end} – t_{start} \)

Where:
\( t_{end} \) = end timestamp
\( t_{start} \) = start timestamp

Conversion to Seconds:
\( s = \frac{\Delta t}{1000} \)

Conversion to Minutes:
\( m = \frac{s}{60} \)

Conversion to Hours:
\( h = \frac{m}{60} \)

Conversion to Days:
\( d = \frac{h}{24} \)
