I parsed it as meaning "[date and time] is equal to UTC plus ten hours", or in other words, "the time specified is in the UTC+10 time-zone". Similarly to how I often seen Eastern Standard Time referenced as UTC-4 (that is, UTC minus four hours). > Normally, you put either the string UTC to indicate that this date/time > string is in UTC, or a time zone offset indicator that begins with + or -. > Not both. It may be notable that he didn't put a +- offset indicator; he put a format specifier which *expands to* whichever such indicator would correspond to the active time zone. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
