+ * Assembled by Jean Rabault
+ * 
+ * UNIX_TIMESTAMP gives the UNIX timestamp (unsigned long integer of seconds since 1st Jan 1970) of compilation from macros using the compiler defined __TIME__ macro.
+ * This should include Gregorian calendar leap days, in particular the 29ths of February, 100 and 400 years modulo leaps.
+ * 
+ * Careful: __TIME__ is the local time of the computer, NOT the UTC time in general!
