      • offsetFromTAI

        <T extends org.hipparchus.RealFieldElement<T>> T offsetFromTAI​(FieldAbsoluteDate<T> date)
        Get the offset to convert locations from TAIScale to instance.
        Type Parameters:
        T - type of the filed elements
        Parameters:
        date - conversion date
        Returns:
        offset in seconds to add to a location in TAIScale time scale to get a location in instance time scale
        Since:
        9.0

        default double offsetToTAI​(DateComponents date,
                                   TimeComponents time)
        Get the offset to convert locations from instance to TAIScale.
        Parameters:
        date - date location in the time scale
        time - time location in the time scale
        Returns:
        offset in seconds to add to a location in instance time scale to get a location in TAIScale time scale

        offsetFromTAI(AbsoluteDate)
      • insideLeap

        default boolean insideLeap​(AbsoluteDate date)
        Check if date is within a leap second introduction in this time scale.

        This method will return false for all time scales that do not implement leap seconds, even if the date corresponds to a leap second in UTC scale.

        Parameters:
        date - date to check
        Returns:
        true if time is within a leap second introduction
      • insideLeap

        default <T extends org.hipparchus.RealFieldElement<T>> boolean insideLeap​(FieldAbsoluteDate<T> date)
        Check if date is within a leap second introduction in this time scale.

        This method will return false for all time scales that do not implement leap seconds, even if the date corresponds to a leap second in UTC scale.

        Type Parameters:
        T - type of the filed elements
        Parameters:
        date - date to check
        Returns:
        true if time is within a leap second introduction
        Since:
        9.0
      • minuteDuration

        default int minuteDuration​(AbsoluteDate date)
        Check length of the current minute in this time scale.

        This method will return 60 for all time scales that do not implement leap seconds, even if the date corresponds to a leap second in UTC scale, and 61 for time scales that do implement leap second when the current date is within the last minute before the leap, or during the leap itself.

        Parameters:
        date - date to check
        Returns:
        60 or 61 depending on leap seconds introduction
      • minuteDuration

        default <T extends org.hipparchus.RealFieldElement<T>> int minuteDuration​(FieldAbsoluteDate<T> date)
        Check length of the current minute in this time scale.

        This method will return 60 for all time scales that do not implement leap seconds, even if the date corresponds to a leap second in UTC scale, and 61 for time scales that do implement leap second when the current date is within the last minute before the leap, or during the leap itself.

        Type Parameters:
        T - type of the filed elements
        Parameters:
        date - date to check
        Returns:
        60 or 61 depending on leap seconds introduction

        Returns:
        value of the previous leap
      • getLeap

        default <T extends org.hipparchus.RealFieldElement<T>> T getLeap​(FieldAbsoluteDate<T> date)
        Get the value of the previous leap.
