246	psSphereTransformEclipticToICRS()	gusciora@…	Paul Price	"In the ADD, the value ""T"" is specified as the time in Julian centuries since 1900.
How should T be calculated?  I currently have this coded:

    struct tm *tmTime = psTimeToTM(&time);
    psF64 year = (psF64)(1900 + tmTime->tm_year);
    psF64 T = year / 100.0;

Is that correct?  Or should I include months and days in this calculation?"	defect	closed	high		PSLib ADD	unspecified	normal	invalid
