@ahutsunshine I've traced time zone logic to your commit, are you aware of
problem described in a ticket? Challenge is that UI format is not in sync with
parsing logic. Basically there are two options:
- fix behavior on backend to understand format
- alternatively we can change UI to use right format
Fixing it on server side might be good (by making existing jobs and
examples created with wrong format to be working), from other hand it might
break compatibility, as jobs with malformed zones will start to run in new time
zone. What's your take on it?
> Wrong sign of time zone offset when created from UI

> Key: GRIFFIN-206
> URL: https://issues.apache.org/jira/browse/GRIFFIN-206
> Project: Griffin (Incubating)
> Issue Type: Bug
> Reporter: Nikolay Sokolov
> Assignee: Nikolay Sokolov
> Priority: Major
>
> When job is created from UI, time zone offset is created by this piece of
> code:
> {code:none}
> let time = new Date().getTimezoneOffset() / 60;
> let timezone = "GMT" + time + ":00";
> {code}
> Problem is, that for GMT-7 it yields positive number, resulting in calculated
> timezone to be GMT+7.
> Turns out that that some formats are not parsed properly, at least UTCXX:XX
> format used by UI is not processed correctly, and GMTXX:XX (without signs):
> {code:none}
> scala> java.util.TimeZone.getTimeZone("GMT6")
> res9: java.util.TimeZone =
> sun.util.calendar.ZoneInfo[id="GMT",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
> scala> java.util.TimeZone.getTimeZone("GMT+6")
> res10: java.util.TimeZone =
> sun.util.calendar.ZoneInfo[id="GMT+06:00",offset=21600000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
> scala> java.util.TimeZone.getTimeZone("UTC+6")
> res11: java.util.TimeZone =
> sun.util.calendar.ZoneInfo[id="GMT",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
> scala> java.util.TimeZone.getTimeZone("UTC-6(CST)")
> res12: java.util.TimeZone =
> sun.util.calendar.ZoneInfo[id="GMT",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
> {code}
