Yeah. CST is a sloppy term; your computer is going to be America/Chicago or America/Indiana/Indianapolis (for the weird one that doesn't use DST), and those are unambiguous. (While researching this comment, I found that Indiana has at least 8 different time zones, so ... good luck with that.) I don't know if you can type things like "CST" into Debian, but I don't think you can.

This defines time zones as the set of clocks that have shared the same time since 1970, so every time an Indiana county decided it wanted to move from Eastern to Central or vice versa, it got split into its own timezone. It reflects a level of precision that is perhaps greater than Indianans themselves actually keep. [Also, FWIW, Indiana does observe DST now.]

> CST is a sloppy term; It's not though, it means "Central Standard Time", which is UTC-06:00. It is sometimes sloppily misused to mean "Central Time", which is a sloppy term, meaning either UTC-06:00 (CST) or UTC-05:00 (CDT) depending on the time of year and where you are in the country. > or America/Indiana/Indianapolis (for the weird one that doesn't use DST) 1. You mean `America/Indiana/Knox` or `America/Indiana/Tell_City` or historically almost any of the other `America/Indiana/…` zoneinfo files except for Indianapolis. Indianapolis has "always" (since 1961) been "Eastern" rather than "Central", it's other non-Indianapolis regions of Indiana that have been "Central, but without DST". 2. But regardless, it's outdated; all of Indiana has been doing DST since 2006; mostly Eastern (EDT/EST), but a few western parts of the state are Central (CDT/CST). > (While researching this comment, I found that Indiana has at least 8 different time zones, so ... good luck with that.) They only still exist for pre-2007 dates; for post-2007 dates they're all equivalent to either America/Chicago (…/Knox and …/Tell_City) or America/New_York (the other 6 of them). > I don't know if you can type things like "CST" into Debian, but I don't think you can. It's inconsistent. You can type in EST or MST, but not CST.
