So, basically we may need a way to (1) identify ambiguous TZ
specifications; (2) signal to user about potential issues.
Note that these are also optional features we may implement any time
once we have basic timezone support.
For (2) we may use something similar to `world-clock' - display user
timestamp at point for different time zones. Maybe via eldoc.
