Convert a Gregorian date to a Julian Day Count; then convert the Julian Day Count to Unix timestamp:
The jdtounix() function converts Julian Day Count to Unix timestamp.
Note: This function will return false if the parameter jd is not inside the Unix epoch (which means that the Gregorian years must be between 1970 and 2037 OR that jd >= 2440588 and jd <= 2465342). The time returned is local time.
Tip: Look at the unixtojd() function to convert Unix timestamp to Julian Day Count.
|jd||Required. A Julian Day number between 2440588 and 2465342|
|Return Value:||Returns the Unix timestamp for the start of the specified Julian day|
