set Wireshark to display UTC timestamps, regardless of the local
timezone, but I'm not aware of any way to force Wireshark to display
any particular (other, i.e. non-zero) timezone offset.

On UN*X systems, you can run Wireshark with the TZ environment variable set to refer to the other time zone - note that a time zone may have more than just an offset, it may have an offset that changes over time, due to daylight savings time/summer time or due to the region changing its offset for other reasons.

The same also works on Windows (if you run Wireshark from a command line). There is also a bug report to allow Wireshark to set the timezone:
