Hello All,
I have been working on a vertical sundial and I have a question.
This South facing vertical has two time scales on it, one at the top
that shows the hour numbers to use during the period of the year when
Standard time is in effect, and one at the bottom to show the hour numbers to
use during the Summer when Daylight Saving time is in effect. The
hourlines will include the appropriate longitude correction for the
site. There is also a complete EoT chart located right under the
shadowfield on the face of the dialplate.
My question is whether or not it would be acceptable to
actually label each scale "Standard Time" or "Daylight Saving Time" so
that casual observers would be able to tell which one to use for
the appropriate time of the year. My understanding is that there are
three things to consider when designing a dial that will indicate
Standard Time: solar time at the reference meridian, longitude correction,
and EoT. Since all three of these things will be dealt with on the dial
face, would it be appropriate to label the time scales?
One of my good sundial friends has commented that technically the
scales do not really indicate true Standard Time/DST because the EoT is not
actually computed into the hourlines. I would be interested to hear what
the consensus is regarding this issue, because I want to do the right
thing. If these exact titles are objectionable does anyone have any
ideas what I might use for alternative labels? I am trying to make a
dial that is easy for "regular people" to understand and use, and
I think some kind of label along the time scales would be helpful to casual
observers.
