172	ADD (Ver 5) Delta UT1 Table Lookups	calvin.harman@…	Paul Price	"Section 1.2.1.5 of the ADD describes an elaborate method for determining UT1- 
UTC, however, within the table (located at 
ftp://maia.usno.navy.mil/ser7/ser7.dat) an equation that gives an approximation 
is listed. Can this equation be used rather than having to possibly filter 
through the two tables referenced in the ADD? 

The value for UT1-UTC ranges from -0.9 to +0.9 seconds, and it isn't clear if a 
complex algorithm is necessary, given that the current epoch time is 1093909314 
seconds and such a small quantity doesn't change this number too much."	defect	closed	high		PSLib ADD	unspecified	normal	fixed
