What's the 'timezone' RPM version (rpm -qa | grep timezone)? -- Pedro Principeza. From: "Veencamp, Jonathon D." <jdveenc...@fedins.com> To: LINUX-390@vm.marist.edu, Date: 04/11/2013 11:24 Subject: Re: Daylight savings time issue Sent by: Linux on 390 Port <LINUX-390@vm.marist.edu> ZVM is showing CDT, Linux is showing CST. (so the clock is an hour off) We use SUSE Linux. Yast2 timezone shows hardware clock set to UTC, and our timezone as Central Time (Chicago). It's like Linux isn't correctly recognizing that Daylight Savings began yesterday. If I change the timezone to Eastern Time, then the local time on Linux is displayed correctly. But that's a workaround and not the correct fix. Still, everything has been working as intended for years, so I'm confused why this is suddenly an issue this IPL.

When you installed Linux did you tell it to use GMT and apply its own offset or use the Local time? One answer I believe uses the hardware clock and the other uses the VMDBK clock for the guest, could be wrong though Larry Davis, VM Capability -----Original Message----- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Veencamp, Jonathon D. Sent: Monday, November 04, 2013 8:12 AM To: LINUX-390@VM.MARIST.EDU Subject: Daylight savings time issue Good morning list, Does anyone have any quick advice? We are in Minnesota and have just switched to Daylight Savings. Someone IPL'd ZVM differently yesterday than on past IPL's. (TOD clock question answered yes). Now we are seeing the correct time in CMS in zVM (I think) but Linux is not showing daylight savings. ZVM query timezone Zone Direction Offset Status UTC ---- 00.00.00 Inactive GMT ---- 00.00.00 Inactive EDT West 04.00.00 Inactive EST West 05.00.00 Inactive CDT West 05.00.00 Active CST West 06.00.00 Inactive MDT West 06.00.00 Inactive MST West 07.00.00 Inactive PDT West 07.00.00 Inactive PST West 08.00.00 Inactive Ready; T=0.01/0.01 07:05:22 <-- This is correct. zLinux # date Mon Nov 4 06:05:35 CST 2013 <-- So CST is the issue. I verified that /etc/timezone is set to the same as /usr/share/zoneinfo/America/Chicago. Our TZ environmental variable is not set. Any advice?
