TIMESTAMPDIFF() 
This function is used to return a value after subtracting a DateTime expression
from another

Syntax :
TIMESTAMPDIFF(unit,expr1,expr2)

Example 1 :
SELECT TIMESTAMPDIFF(SECOND, '2010-01-01 10:10:20', '2010-01-01 10:45:59') 
AS SecondDiff; #Output: 2139
Example 2:
SELECT TIMESTAMPDIFF(SECOND, '2010-01-01 10:10:20', '2010-01-01 09:45:59') 
AS SecondDiff; #Output: -1461
Example 3:
SELECT TIMESTAMPDIFF(MONTH, '2019-08-01', '2020-11-01') AS MonthDiff;
#Output: 15

//========== Convert function ==========//
function convertGpsToSvgPoints(coordinates: Coordinate[], viewBoxSize = 200): string {
  if (coordinates.length === 0) return "";

  // Find the bounds of the coordinates
  const lats = coordinates.map((coord) => coord.latitude);
  const longs = coordinates.map((coord) => coord.longitude);

  const minLat = Math.min(...lats);
  const maxLat = Math.max(...lats);
  const minLong = Math.min(...longs);
  const maxLong = Math.max(...longs);

  // Calculate the range
  const latRange = maxLat - minLat;
  const longRange = maxLong - minLong;

  // Convert coordinates to SVG points
  const points = coordinates.map((coord) => {
    // Normalize to 0-1 range
    const x = (coord.longitude - minLong) / longRange;
    const y = (coord.latitude - minLat) / latRange;

    // Scale to viewbox size and add padding
    const padding = viewBoxSize * 0.1; // 10% padding
    const scaledX = x * (viewBoxSize - 2 * padding) + padding;
    const scaledY = y * (viewBoxSize - 2 * padding) + padding;
