Barycentric Julian Date - Ohio State University
JD and BJD are defined independent of the time standard. JD can be expressed as e.g. UTC, TT, TAI, TDB, etc. The differences between these time standards are of the order of a minute, so for better than one-minute accuracy, the time standard must be stated. While many quote the BJD in UTC, UTC is discontinuous and drifts with the addition of each leap second, and should therefore only be used for relative timing over a short time span (~1 year). For high-precision, absolute ti… WebThe Time object maintains an internal representation of time as a pair of double precision numbers expressing Julian days.
