The build logs dates default to 01-Jan-1970 01:00:00 if the windows display format is different from the system locale

Summary

If locale setting in the Bamboo Server computer makes the date use a special character, Bamboo will fail to parse the date, returning null.

Environment

Linux with locale settings that use special characters for either days or months.

Steps to reproduce

1. In catalina.sh (for Linux), add "user.language=XX" for JAVA_OPTS. For example:

   JAVA_OPTS="$JAVA_OPTS $JSSE_OPTS -Duser.language=de -Duser.region=DE"
   

   We are now in March. In german, March is März. The "umlaut" cannot be parsed.

2. Run a build.

Expected results

03-Mar-2017 16:33:55 	JOB1
03-Mar-2017 16:33:55 	going to sleep.
03-Mar-2017 16:33:58 	sleeping done

Actual results

01-Jan-1970 01:00:00 	JOB1
01-Jan-1970 01:00:00 	going to sleep.
01-Jan-1970 01:00:00 	sleeping done

Workaround

1. Force tomcat to use english locale:

   JAVA_OPTS="$JAVA_OPTS $JSSE_OPTS -Duser.language=en -Duser.region=DE"

Steps to replicate

1. Set your system locale to US or UK locale
2. Set the region format to German de-CH. See the screenshot
   
3. This will cause Bamboo build logs to display the logs all to default date 01-Jan-1970 01:00:00. If the build logs is hwoever opened or downloaded, the correct timing is shown. See below
   
4. This mostly happens in months when the abbreviations are different. In the example above, December is abbreviated as dec in UK/US whereas in German, it dez. For more on the list of month abbreviations see http://library.princeton.edu/departments/tsd/katmandu/reference/months.html
