User talk:Hazelorb/Time zone

A History of the International Date Line

1. How are time zones bounded by longitude? 2. How were they legally mandated? 3. What are the legally mandated time zones? 4. What is UTC and how did it contribute to time zones?

Local time in each time zone is UTC plus the current time zone offset for the location in question. unnecessary in intro or rephrase or blend into prev sent

5. What order do the days go, how did this (intl date line) come about? and rephrase

A corresponding one hour decrease relative to UTC occurs every 15° heading westward from the western boundary of the UTC time zone, up to the International Date Line. this can be blended into 4 and 5.

Not included: computers

1. More about DST (and "summer time zones") 2. need (move to) pic about dividing, good. section should be on "How time zones are divided" or otherwise -- includes geo and politics (so #1&2 from above) -- 1 is completely covered with this sentence + pic

3. pre-time zones in history -- subsection

4. why they developed in the first place why they change and how they chose -- goes with #2 from above why they are still changing today

not mentioned; UTC, intl dateline == How were timezones standardized?

Standard time zones: -- rename Standardization of Time Zones Include: UTC, intl dateline A lot of this content should not be here. 1. this is about standardization of time zones -- no 2. same 3. same 4. same

picture -- with division of time zones

Notation of time (ISO 8601) --Rename to Notations and Abbreviations --first big see also of ISO 8601, abbrev list, and UTC offset

rewrite....

Examples move chart to whatever becomes main "see also: list of timezones by utc offset" others: section: intl date line

time zone conversions => examples

history = break into sections outlined above... go from there

nautical--put in at end, not sure where to put yet

skewing = part of history/current... fit into and go from there

DST... expand... + see also: dst around the world

additional info == some => skewing, countries => "see also: list by countries" the one about "see also by utc offset" to that section

that chart => new section UTC and country timezones (or 2 sep sectns)??
