Josh Rosen updated SPARK-15723:
-------------------------------
Issue Type: Sub-task (was: Bug)
Parent: SPARK-15834
> SimpleDateParamSuite test is locale-fragile and relies on deprecated short TZ
> name
> ----------------------------------------------------------------------------------
>
> Key: SPARK-15723
> URL: https://issues.apache.org/jira/browse/SPARK-15723
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 1.6.1
> Reporter: Brett Randall
> Assignee: Brett Randall
> Priority: Minor
> Labels: test
> Fix For: 1.6.2, 2.0.0

>
> {{org.apache.spark.status.api.v1.SimpleDateParamSuite}} has this assertion:
> {code}
> new SimpleDateParam("2015-02-20T17:21:17.190EST").timestamp should be
> (1424470877190L)
> {code}
> This test is fragile and fails when executing in an environment where the
> local default timezone causes {{EST}} to be interpreted as something other
> than US Eastern Standard Time. If your local timezone is
> {{Australia/Sydney}}, then {{EST}} equates to {{GMT+10}} and you will get:
> {noformat}
> date parsing *** FAILED ***
> 1424413277190 was not equal to 1424470877190 (SimpleDateParamSuite.scala:29)
> {noformat}
> In short, {{SimpleDateFormat}} is sensitive to the local default {{TimeZone}}
> when interpreting short zone names. According to the {{TimeZone}} javadoc,
> they ought not be used:
> {quote}
> Three-letter time zone IDs
> For compatibility with JDK 1.1.x, some other three-letter time zone IDs (such
> as "PST", "CTT", "AST") are also supported. However, their use is deprecated
> because the same abbreviation is often used for multiple time zones (for
> example, "CST" could be U.S. "Central Standard Time" and "China Standard
> Time"), and the Java platform can then only recognize one of them.
