pacific time (us & canada) how 1 parse timezone or datetimezone on jvm? i've tried timezone.gettimezone , datetimezone.forid no avail.
it appear yammer returns timezone field part of user object in rest api. example can seen part of the authorization docs in response body in section labeled "c. app authentication", , looks like:
{ "user": { "timezone": "hawaii", "interests": null, "type": "user", ... this returned of get /users/... apis. experimenting, can see value returned api corresponds keys of drop-down list appears in user account settings screen (found @ https://yammer.com/<your domain>/account/display_options) :
when view source of web page, can see drop-down list of keys , values:

keys partial bits of windows time zone display names. they're not distinct identifiers in windows, or microsoft technology. puzzled why yammer choose these time zone ids. way go follows:
look @ cldr windows zone mapping file. you'll see entries such as:
<!-- (utc-08:00) pacific time (us & canada) --> <mapzone other="pacific standard time" territory="001" type="america/los_angeles"/> <mapzone other="pacific standard time" territory="ca" type="america/vancouver america/dawson america/whitehorse"/> <mapzone other="pacific standard time" territory="mx" type="america/tijuana"/> <mapzone other="pacific standard time" territory="us" type="america/los_angeles"/> <mapzone other="pacific standard time" territory="zz" type="pst8pdt"/> <!-- (utc-07:00) arizona --> <mapzone other="us mountain standard time" territory="001" type="america/phoenix"/> <mapzone other="us mountain standard time" territory="ca" type="america/dawson_creek america/creston"/> <mapzone other="us mountain standard time" territory="mx" type="america/hermosillo"/> <mapzone other="us mountain standard time" territory="us" type="america/phoenix"/> <mapzone other="us mountain standard time" territory="zz" type="etc/gmt+7"/> <!-- (utc-07:00) chihuahua, la paz, mazatlan --> <mapzone other="mountain standard time (mexico)" territory="001" type="america/chihuahua"/> <mapzone other="mountain standard time (mexico)" territory="mx" type="america/chihuahua america/mazatlan"/>search yammer time zone key in comment lines, partial substring match. example, if yammer time zone
"la paz", match entry comment<!-- (utc-07:00) chihuahua, la paz, mazatlan -->take iana time zone id next line following comment. 1 marked
territory="001". wanttypefield. previous example,"america/chihuahua".you can use id in java of standard java 7 or java 8 apis (or joda time).
one last point. checked (via users api) timezone setting of many people in own yammer network know in other time zones, , few had ever changed time zone "pacific time (us & canada)" default setting. therefore, suspicious trust these values accurate. far can tell, there's nothing force yammer user change setting default, , have go out of way it.
