Improve tz command
- "tz me <my-time-zone>" command to configure per-user time zone
- "tz alias add <alias> <zone-name>" command to add system aliases
- "tz alias rm <alias>" command to remove system aliases
- target time zone command "tz <date> <time> <zone1> to <zone2>,<zone3>,..."
  (without zone2+, it converts to user's own time zone, or direct user to use tz me command)
