Went with UI route for a time being, to avoid introducing any incompatible
behavior from backend side.
> 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}
