long	currentProcessingTime() Returns the current processing time.
long	currentWatermark() Returns the current event-time watermark.
java.time.ZoneId	getShiftTimeZone() The shift timezone of the window, if the proctime or rowtime type is TIMESTAMP_LTZ, the shift timezone is the timezone user configured in TableConfig, other cases the timezone is UTC which means never shift when assigning windows.
void	registerEventTimeWindowTimer(Long window) Registers a window timer to be fired when event time watermark passes the window.
void	registerProcessingTimeWindowTimer(Long window) Registers a window timer to be fired when processing time passes the window.
