Calculates time intervals and returns the start of the interval nearest to the specified timestamp. Use `date_bin` to downsample time series data by grouping rows into time-based "bins" or "windows" and applying an aggregate or selector function to each window.

For example, if you "bin" or "window" data into 15 minute intervals, an input timestamp of `2023-01-01T18:18:18Z` will be updated to the start time of the 15 minute bin it is in: `2023-01-01T18:15:00Z`.
