     * Symbol of temporal unit used by `spacing[0]`, e.g. "hr".
     *
     * If units match one of the following, the viewer will automatically format
     * timestamps to a d:hh:mm:ss.sss format, truncated as an integer of the unit specified.
     * See https://ngff.openmicroscopy.org/latest/index.html#axes-md for a list of valid time units.
     * - "ms", "millisecond" for milliseconds: `d:hh:mm:ss.sss`
     * - "s", "sec", "second", or "seconds" for seconds: `d:hh:mm:ss`
     * - "m", "min", "minute", or "minutes" for minutes: `d:hh:mm`
     * - "h", "hr", "hour", or "hours" for hours: `d:hh`
     * - "d", "day", or "days" for days: `d`
     *
     * The maximum timestamp value is used to determine the maximum unit shown.
     * For example, if the time unit is in seconds, and the maximum time is 90 seconds, the timestamp
     * will be formatted as "{m:ss} (m:s)", and the day and hour segments will be omitted.
