When you setup the right axis labeling, apply a rule to the data format.Supported formats include "numeric" where data is treated as numeric, "timestamp" where values are interpreted as UNIX timestamps (number of seconds since January 1970) and expressed using strftime format (default is "%Y-%m-%d %H:%M:%S").See also --units-length and --right-axis-format.Finally "duration" where values are interpreted as duration in milliseconds.Formatting follows the rules of valstrfduration qualified PRINT/GPRINT.
