Concrete methods
Calculates the difference between this time scale and TAI at the given time.
Calculates the difference between this time scale and TAI at the given time.
Attributes
- Definition Classes
Inherited methods
Returns the most recent leap second adjustment applied to this time scale.
Returns the most recent leap second adjustment applied to this time scale.
For time scales without leap seconds, this returns zero.
Attributes
- Returns
-
The most recent leap second adjustment as a TimeFormat
- Inherited from:
- TimeScale
Retrieves the leap second adjustment for the given absolute time.
Retrieves the leap second adjustment for the given absolute time.
Value parameters
- time
-
The absolute time for which to determine the leap second adjustment.
Attributes
- Returns
-
The leap second adjustment as a TimeFormat instance.
- Inherited from:
- TimeScale
Gets the identifying name of this time scale.
Gets the identifying name of this time scale.
Attributes
- Returns
-
The name of this time scale (e.g., "UTC", "TAI", "TT")
- Inherited from:
- TimeScale
Determines if a given absolute time falls within a leap second.
Determines if a given absolute time falls within a leap second.
For time scales that don't use leap seconds (like TAI), this always returns false. For UTC, this would return true during leap second events.
Value parameters
- time
-
The absolute time to check
Attributes
- Returns
-
true if the time is inside a leap second, false otherwise
- Inherited from:
- TimeScale
Duration of a minute in seconds. Default is 60 seconds for most time scales. May differ for specialized astronomical time scales.

Attributes
- Inherited from:
- TimeScale
Converts a date and time in this scale to the equivalent TAI time.
Converts a date and time in this scale to the equivalent TAI time.
This method iteratively converges on the correct offset using the timePastTAI function. It typically requires 3-4 iterations to converge with sufficient accuracy.
Value parameters
- date
-
The date component in this time scale
- time
-
The time component in this time scale
Attributes
- Returns
-
The offset to add to the input time to get TAI
