pyarrow.compute.milliseconds_between

pyarrow.compute.milliseconds_between(start, end, /, *, memory_pool=None)

Compute the number of millisecond boundaries between two timestamps.

Returns the number of millisecond boundaries crossed from start to end. That is, the difference is calculated as if the timestamps were truncated to the millisecond. Null values emit null.

Parameters:

startArray-like or scalar-like

Argument to compute function.

endArray-like or scalar-like
