        "DESCRIPTION": {
            "content": "This module parses the Olson database time zone definition files and creates various objects\nrepresenting time zone data.\n\nEach time zone is broken down into several parts. The first piece is an observance, which is an\noffset from UTC and an abbreviation. A single zone may contain many observances, reflecting\nhistorical changes in that time zone over time. An observance may also refer to a set of rules.\n\nRules are named, and may apply to many different zones. For example, the \"US\" rules apply to\nmost of the time zones in the US, unsurprisingly. Rules are made of an offset from standard time\nand a definition of when that offset changes. Changes can be a one time thing, or they can recur\nat regular times through a span of years.\n\nEach rule may have an associated letter, which is used to generate an abbreviated name for the\ntime zone, along with the offset's abbreviation. For example, if the offset's abbreviation is\n\"C%sT\", and the a rule specifies the letter \"S\", then the abbreviation when that rule is in\neffect is \"CST\".\n",
