Enum Constant Summary

Enum Constants

Enum Constant	Description
ET	Ephemeris Time; predecessor of, and continuous with, TT
GMST	Greenwich Mean Siderial Time; only for ground-based observations; note that the second is shorter
GPS	Global Positioning System's time scale; runs 19 s behind TAI, 51.184 s behind TT.
IAT	Synonym for TAI
LOCAL	Only to be used for simulations in conjunction with a relocatable spatial frame
LST	Local Siderial Time; only for ground-based observations; note that the second is shorter
TAI	International Atomic Time; runs 32.184 s behind TT
TCB	Barycentric Coordinate Time; runs slower than TDB but is consistent with physical constants
TCG	Terrestrial Coordinate Time
TDB	Barycentric Dynamic Time:the independent variable in planetay ephemerides; time at the solar system barycenter synchronous with TT on an annual basis; sometimes called TEB
TDT	Obsolete synonym for TT
TEB	Barycentric Ephemeris Time: time at the solar system barycenter synchronous with TT on an annual basis; a deprecated synonym of TDB.
TT	Terrestrial Time; the basis for ephemerides
UTC	Coordinated Universal Time; currently (2006) runs 33 leapseconds behind TAI

Method Summary

Modifier and Type	Method	Description
String	enumValue()

Method Details

values

public static TimeScaleType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static TimeScaleType valueOf(String name)

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
