Subject : Use of UTC in Marine Forecast and Shipping Warning
In current practice, the Greenwich Mean Time ("GMT") which lags
behind the Hong Kong standard time by 8 hours, is used in Marine
Forecast and Shipping Warning.
Please be informed that with effect from 16 May 2005, all times
currently expressed in GMT shall be changed to Coordinated Universal
Time ("UTC"). Theoretically, UTC is a refinement of GMT. However,
for general operational purpose, their difference should be negligible.
Hence, you may take UTC and GMT to be the same. Notwithstanding this,
your attention is drawn on the change from "GMT" to "UTC" in the webpages.
Should you be interested, more information about GMT and UTC may be found
in the following web pages:
