Best I can do is what I've done here:
- improved CPGNuCal so that it reflects the same site setting as the Forums.
- show your personal difference from that setting.
- Here the board timezone is set at GMT + DST
- CPGNuCal now adopts the same base setting of GMT + DST
- Lets say you were in Hawaii, which is -10 GMT, no DST
- CPGNuCal tells you "Your time adjustment -10:00"
Changing individual event times to reflect your personal timezone requires a significant re-write that I'm not prepared to spend time on.
