Defines the arithmetic kernels for adding a Duration to a Timestamp, Time32, Time64, Date32 and Date64.
For the purposes of Arrow Implementations, adding this value to a Timestamp (“t1”) naively (i.e. simply summing the two number) is acceptable even though in some cases the resulting Timestamp (t2) would not account for leap-seconds during the elapsed time between “t1” and “t2”. Similarly, representing the difference between two Unix timestamp is acceptable, but would yield a value that is possibly a few seconds off from the true elapsed time.
Functions
Adds a duration to a time array (Timestamp, Time and Date). The timeunit enum is used to scale correctly both arrays; adding seconds with seconds, or milliseconds with milliseconds.
Adds a duration to a time array (Timestamp, Time and Date). The timeunit enum is used to scale correctly both arrays; adding seconds with seconds, or milliseconds with milliseconds.
Adds an interval to a DataType::Timestamp.
Adds an interval to a DataType::Timestamp.
Subtract a duration to a time array (Timestamp, Time and Date). The timeunit enum is used to scale correctly both arrays; adding seconds with seconds, or milliseconds with milliseconds.
Calculates the difference between two timestamps as DataType::Duration with the same time scale.
Subtract a duration to a time array (Timestamp, Time and Date). The timeunit enum is used to scale correctly both arrays; adding seconds with seconds, or milliseconds with milliseconds.
Calculates the difference between two timestamps returning an array of type Duration. The timeunit enum is used to scale correctly both arrays; subtracting seconds with seconds, or milliseconds with milliseconds.
