java - JVM has incorrect timezone after installation of jdk 8 -


i have tomcat service on centos server, , time sensitive service. jvm has gotten timezone correctly until installed jdk 8 yesterday.

to fix have add "-duser.timezone=gmt+8" after java command, feel inconvenient.

i use date command on server , gives correct timezone. curious: 1. cause problem 2. , how solve neatly?

thank in advance.

here comes test info:

[chiming1@localhost test]$ date +'%y%m%d %h:%m:%s %z'   20170920 15:01:20 +0800   [chiming1@localhost test]$ java  -duser.timezone=gmt+08 javatest/test   2017-09-20 15:01:34   gmt+08:00   gmt+08:00   [chiming1@localhost test]$ java javatest/test   2017-09-20 07:01:48   greenwich mean time   gmt   [chiming1@localhost test]$ java -version   java version "1.8.0_144"   java(tm) se runtime environment (build 1.8.0_144-b01)   java hotspot(tm) 64-bit server vm (build 25.144-b01, mixed mode)

and java test code is:

simpledateformat sdf = new simpledateformat("yyyy-mm-dd hh:mm:ss");   date d = new date();   system.out.println(sdf.format(d));   timezone tz = timezone.getdefault();   system.out.println(tz.getdisplayname());   system.out.println(tz.getid());

can post example of output? if in format of 2016-07-11t11:01:25.498z in utc time (if ends in z utc).

you can use system.setproperty("user.timezone", "gmt+8"); or add environment variable defaults "gmt+8"
