I imagine we could also do some other terms too.

Quarter of 10 means 15 minutes to 10.

Zulu is used the same as UTC and GMT. Zulu is more of a military term.

Interestingly, the term "O'Clock" is a term that has survived in English
since mediaeval times. It is a contraction of "of the clock". So, for
example, "nine o'clock" is a shortened version of nine of the clock".

Your post raises an interesting topic. The relation between the sun, a
compass and an analogue watch (or clock) is an equation. If you have any two
of these three items, the third can be determined.

For example, if you can see the sun, and you are wearing an analogue watch,
you can determine true North. Or, if you have a compass, and you can see the
sun, you can determine what time it is.

Remember, that it is a watch or clock that is used to determine longitude
also. First, you set your watch to midday exactly as the sun reaches the
highest point in the sky (Note: your watch is now set to sidereal time and
not mean time).

Next, sail (for simplicity) due East. Next day, when the sun is at its
highest, see what the time is on your watch. Let's say its 11 o'clock. Then
you have travelled 15 degrees East of where you started (remembering that
360 degrees of longitude divided by 24 hours is 15 degrees per hour).

No navigator would be seen without his/her analogue watch!

Finally, a question: There is a time zone in the world which is set to UTC.
And there are 12 times zones which are ahead of UTC (+1, +2, etc) (and, yes,
some partial hour variations too). And there's 12 timezones which are less
than UTC (-1, -2, etc). That adds up to 25 time zones. Yet there's only 24
hours in a day! What's going on? (Hint: the timezone at my location holds
the answer)

Yes. The +12 hours and the -12 hours are of course the same time. But on
different dates.

No, nothing new as such. Some activity re ICE flights on 9032, the usual for
this time of the year I suppose.

What have you been listening to lately? Something interesting?

Nothing much of interest here at the moment. Soon I'll be looking for Indian

This is far from exact, based on the equation of time, which
is not reflected on the watch. Local solar time, mean solar time and

Actually it's set to solar time. A solar day does not

drift with respect to each other.

Yes, you're right, its far from exact. If you want it to be exact then
you'll need the compass after all. Oh, and if you want true North then
you'll need to know the magnetic variation at your current location. And to
help you know your current location, you'll need the compass.... etc. I
suppose I was outlining a rule of thumb, perhaps to be used in an emergency
situation, or simply as an exercise to demonstrate such relationships
between the three.

Again, thanks for the correction. Better not rely on me if you get lost!
