The subject of time just keeps growing and growing...........
NZ is in time zone -12 ( Admiralty Manual of Navigation).
When NZST is in use zone time is UTC + 12. When NZDT is in use zone time is UTC + 13. Currently NZDT is in use.
When I have given details of an observation I have given my time as, for example, 13:43:56 (zone -13). Clearly that is incorrect as there is no zone -13. Should I give my time as:
13:43:56 (zone -12, NZDT)
13:43:56 (UTC + 13)
13:43:56 (zone -13) because -13 is added to zone time to get UTC. This is the time zone sign convention.
or some other format?
