def ts_plot(variable, ds, fs, label, reg='Global'):
    """
    Plot time series of regional means and integrals for a given variable from a list of datasets.

    Parameters
    ----------
    variable : str
        Name of the variable to plot (prefix for "_mean" and "_int" variables in dataset).
    ds : list of xarray.Dataset
        List of datasets, each containing time series data for the specified variable with
        variables named as `<variable>_mean` and optionally `<variable>_int`, and with
        attributes 'long_name', 'units_mean', and optionally 'units_int'.
    fs : tuple
        Figure size (width, height) in inches for the plots.
    label : list of str
        List of labels corresponding to each dataset, used for the legend.
    reg : str, optional
        Name of the region to select for plotting (default is 'Global').

    Returns
    -------
    None
        Displays the plots but does not return any value.

    Notes
    -----
    - This function creates one or two plots:
        1. A time series of the variable's regional mean (`<variable>_mean`).
        2. If available, a time series of the variable's regional integral (`<variable>_int`).
    - The function expects each dataset to have attributes 'long_name', 'units_mean', and optionally 'units_int'.
    - The same region name is applied across all datasets.
