- Method Detail
  - values
```
public static TimeSystem[] 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 (TimeSystem c : TimeSystem.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static TimeSystem valueOf(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:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getKey
```
public String getKey()
```
    Get the 3 letters key of the time system.
    
    Returns:
    
    3 letters key

  - parseTimeSystem
```
public static TimeSystem parseTimeSystem(String s)
                                  throws OrekitIllegalArgumentException
```
    Parse a string to get the time system.
    The string must be the time system.
    
    Parameters:
    
    s - string to parse
    
    Returns:
    
    the time system
    
    Throws:
    
    OrekitIllegalArgumentException - if the string does not correspond to a time system key
  - parseTwoLettersCode
```
public static TimeSystem parseTwoLettersCode(String code)
                                      throws OrekitIllegalArgumentException
```
    Parse a string to get the time system.
    The string must be the two letters code of the time system.
    
    Parameters:
    
    code - string to parse
    
    Returns:
    
    the time system
    
    Throws:
    
    OrekitIllegalArgumentException - if the string does not correspond to a time system key
  - parseOneLetterCode
```
public static TimeSystem parseOneLetterCode(String code)
                                     throws OrekitIllegalArgumentException
```
    Parse a string to get the time system.
    The string must be the one letters code of the time system. The one letter code is the RINEX GNSS system flag.
    
    Parameters:
    
    code - string to parse
    
    Returns:
    
    the time system
    
    Throws:
    
    OrekitIllegalArgumentException - if the string does not correspond to a time system key
  - getTimeScale
```
public TimeScale getTimeScale(TimeScales timeScales)
```
    Get the time scale corresponding to time system.
    
    Parameters:
    
    timeScales - the set of time scales to use
    
    Returns:
    
    the time scale corresponding to time system in the set of time scales
