; The SofaJpl DLL uses the US Naval Observatory leap second table format, with ; a few extensions. ; 1. Any line beginning with a semicolon is ignored. ; 2. To make the table easy to update by hand, the JD field is ignored and ; may be blank. ; 3. The last line specifies the end of the table's time span. (More precisely, ; it indicates the first *illegal* UTC date.) The last line must have the same ; TAI-UTC as the previous line but a different date. You should set the ; date a safe amount in the future (before the next leap second) so an error ; message will occur if you forget to update the table. If leap seconds are ; abolished, set the date in the extreme future. 1961 JAN 1 =JD 2437300.5 TAI-UTC= 1.4228180 S + (MJD - 37300.)
