The alt.horology Usenet newsgroup concerns all aspects of horology (the science of time and timekeeping, clocks and watches). Those posting to it range from novices to collectors to professional watchmakers and clockmakers.
This newsgroup was started by Ian Crocker in the United Kingdom during November 1994, as a response to the absence of any newsgroup covering this subject at the time. Early objections to this newsgroup noted that the rec.antiques or sci.physics discussion could support horology discussions, but the creation of alt.horology prevailed. The original intent was only to support the discussion of clocks, watches and time measuring devices.
