The formula to calculate the Local Mean Time (LMT) is:
\[ \text{LMT} = \text{GMT} + \text{ZD} \]
Where:
Local Mean Time (LMT) is the time at a specific location, calculated by adding the zone description (ZD) to the Greenwich Mean Time (GMT). It accounts for the time difference between the location and the prime meridian (0° longitude).
Let's assume the following values:
Using the formula:
\[ \text{LMT} = 12:00 + 3 = 15:00 \]
The Local Mean Time (LMT) is 15:00.
Let's assume the following values:
Using the formula:
\[ \text{LMT} = 18:00 - 5 = 13:00 \]
The Local Mean Time (LMT) is 13:00.
