U.S. military timekeeping during the WW II campaigns in the Pacific
Hi all, Perhaps this topic is a bit off list but does anyone on the list know how the U.S. armed forces set their clocks and watches during the Pacific campaigns from 1942 to 1945? Did they adopt a common time zone (Hawaii, Midway, UT, UT+12h) or did they adopt the time zone of the region that they happened to be operating in? Are there any official documents that can provide more information? I am interested in this question as I am currently doing some research on timekeeping in the former Dutch East Indies (Indonesia) and I know that during the Japanese occupation the whole region was forced to adopt the time zone of Tokyo (UT+9h). I assume that this was also so in the other territories occupied by the Japanese so that military operations directed from Tokyo could be co-ordinated more efficiently. But what was the Americans practice, I wonder? If anyone knows, I would be grateful to hear of it. Thanks in advance, === * Robert H. van Gent * * E-mail: [EMAIL PROTECTED] * * Homepage: http://www.phys.uu.nl/~vgent/homepage.htm * === -
A new sundial - type from Bremen!
may I invite you to have a look at a probably new type of sundial, an analemmatic equatorial sundial with light-pointer, built by my friend Dietrich Ahlers. His HALBE - ACHT - sundial can be seen at the Homepage of Olbers-Planetarium Bremen as sundial of the month March.

Re: A new sundial - type from Bremen!
Hi Reinhold, An excellent dial - thank you for sharing it with us. Being pedantic, I would describe it as analemmic dial, rather than an analemmatic one, but that doesn't detract from its quality. Regards, John Davis -

Re: A new sundial - type from Bremen!
Dear Reinhold, Thank you for your link to the new sundial at the site of Planetarium Bremen. It's a beautiful sundial and I enjoy it very much. But There is a but. The dial is called an "analemmatic equarorial sundial with light-pointer". No problems with "equarorial sundial with light-pointer" but with the word "analemmatic" in this sentence. An analemmatic sundial is a quit different type. Usual it is an horizontal dial with vertical gnomon on a scale of date and hourpoints on an ellips. I understand the "error" because in English the word analemma is also used for the EoT curve. So my advice is not to use the word "analemmatic" in the description of this dial. Thanks for sharing this nice sundial with us. Best wishes, Fer.

Re: A new sundial - type from Bremen!
Oh, it's a really nice one, but as far as I remember, there is a hint in Rafael Soler's book on a dial like these (in the chapter about equatorial sundials). Anyhow, it's just a hint, not the whole device as you show.

Only some minutes after I had sent my message, Fred Sawyer told us about the patent of 1867 :-) So: If you read the German text, Dieter Vornholz writes in his text, that a similar sundial was not known to him. The list is really a very good place to get to know such things! The sundial, which my friend Dietrich Ahlers has built, was made for a client in Bavaria. He wanted to have a sundial, which works both in his hometown Wuerzburg and in Bangkok! - As he intended to present it to a friend in Thailand. Best Reinhold * ** *** * ** *** Reinhold R.

More PDF Advantages
Hi All I often email drawings and pictures of sundials to clients and people on this list. But I always have to be careful not to send too many at once, or my email will reject my mail for being too large. To email photographs, I use JPEG format. And to send Delta Cad drawings I scanned the drawing and send it as a JPEG. I had always thought that JPEGs where the best format to use for emailing because the files are small and everybody can open them. It occurred to me to compare the file size of a typical JPEG photo to the same photo in PDF format (I thought for sure the PDF would be the larger). To my amazement, the PDF file was 20% of the size of the JPEG! The JPEG was 240 KBs. and the PDF was only 46 KBs. This allows me to quickly email more pictures on my crummy 56K modem. As for emailing Delta Cad drawings, now I don't have to scan them and send as JPEGs. I can save and send these as PDFs too, and the quality is much better than a scanned JPEG. Perhaps PDFs will replace JPEGs as the photo format of choice in the future. What do you think? John John L. Carmichael Jr. Sundial Sculptures 925 E.
