A locale-aware time-axis / tooltip formatter. Returns a function mapping a
Unix-seconds timestamp to a localized label whose granularity follows
resolution (see DateResolution). Times are rendered in UTC to
match the default formatTime (and because OHLCV candle times are
exchange-UTC); pass a timeZone to override.
Non-finite / invalid timestamps → '' (axis-safe, like the default).
