“Time Machine” — the unique date converter for world coin collectors.

Hi! My name is Andrei Tretyakov.

I wanna share with you the web application I've created specially for coin collectors. It is called "Time Machine" and available via the following link: http://apps.creounity.com/time_machine/en/.

This webapp is a date converter covering 17 chronological systems. It is capable of converting year from any of the calendars provided in the app to the Gregorian calendar, and backwards (from the Gregorian calendar to a system you want).

With Time Machine it is very easy to find out the production year of your foreign coins.

Along with the converter itself, this app contains pieces of the explanatory texts that could help you understand how does the converter work, as well as learn some facts about chronologies' history and origins.

Time Machine is completely freeware for end users, and doesn't contain ads.

Originally it's been developed by me for Russian and Russian-speaking collectors, but today, on October 31nd, 2010, I've finished working over the translation, and now it has both English and Russian interface languages, all the converter-related articles are available in these two languages as well.

In the nearest future I will add 4 new chronological systems into the Time Machine. Some minor bugs will be fixed. A set of large-size images will be added to each system. Two additional functionalities are under development and I believe they'll be released by the end of 2010.

Have a good time with my "Time Machine", and happy converting!

Thank you! This will be very useful.

 

Awesome!

 

Good site! I like how it's pretty much plug and play with the numbers.

 

I find it very usefull and easy to use. Very good interface. I will recommend it to some friends.

Congratulations.

 

Descriptive articles to the 4 new systems officially added today (Nov. 10, 2010), links to them provided below the main menu, entitled "Systems under development". Other new features are in the process of creation, expected to be released in the following two months. Be ready

 

Nice app, and will come in very handy!
Thanks!!

 

Hm, isn't the 20 chon from my collection?

 

Yea, I've mentioned in the bottom of the Korean page, that, quote: "Some image samples and info about the emperors were taken from gxseries.com" If you don't want your image to be an example on the Korean page, I'll remove it.

 

It's not a problem Andrei. I'm just suprised that you chose a worn example instead of better ones that I have in my collection for example this:



Nevertheless, it's very well written and good job for putting all the time and effort in!

 

Thank you, I'm glad that you appreciate it!

I was making drafts this summer and was searching for at least appropriate pic (one that suits the description) at that time, not the best one. Now, would it be ok if I replace the currently uploaded shabby 20-chon coin with the last provided here by you, that looks fresher?

 

Of course, feel free to use what you need. http://www.gxseries.com/numis/koreatype/koreatype.htm or my album at omnicoin.com

It hasn't been updated for a while and I bought a couple more new coins. Finally finished the difficult half won set.

That must be very difficult and time-consumimg for you to collect by types and make complete sets... I've been collecting coins since I was 8, the area being the world coins, so the point for me since then is getting at least one coin from every country and territory of the world. Now, 16 years later, my 1799 coins cover 243 different countries.

 

I've released some updates for the English version of the Time Machine, here they are:

Thank you. Great stuff, I added it to my popular sites, very useful indeed.

Though I've verified their descriptive parts thoroughly, mistakes are possible. So if you find there any mistake, please let me know about 'em as soon as possible.

 

This is very cool, I will take a look at it in detail later on this evening. I appreciate your hard work.

 

Thank you!

 

Great utility, inscriptor! A vote of thanks!
