Enum Constant Summary

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 Detail

values

public static TimeScaleType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TimeScaleType c : TimeScaleType.values())
    System.out.println(c);

Returns:

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

valueOf

public static TimeScaleType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

value

public java.lang.String value()

fromValue

public static TimeScaleType fromValue(java.lang.String v)
