optivgi.utils.round_down_datetime(dt, minute)

Rounds a datetime object down to the nearest specified minute interval.

For example, rounding 2023-10-27 15:37:45 down with a minute interval of 15 would result in 2023-10-27 15:30:00. Rounding down with an interval of 1 results in rounding down to the start of the current minute.

Parameters:

  • dt (datetime) – The datetime object to round down.

  • minute (int) – The minute interval to round down to (e.g., 1, 5, 15, 60).

Returns:

datetime – The datetime object rounded down to the specified minute interval.

Raises:

ValueError – If minute is not a positive integer.
