Comware

Hello,

I wonder about the summertime settings, and the infofrmation in the manual regarding this.

Reading the "HP7500 Switch Series Fundamentals Configuration Guide R6700"  - "Changing the system time" did not make me any smarter...

] clock summer-time CEST ?

The "?"-help says: 

"one-off        Configure absolute summer time"

"repeating    Configure recurring summer time"

a "one-off" summertime setting? Why?  (Ok Lets accept that for a sec)

Anyways - I use the "repeating" option where I'm promted for a START TIME and END-TIME, but start and end contains YEAR, which much be the same for START and END,  otherwise the command is not accepted.

I guess what I'm asking is: "What is up with that?"

I entered the year 2000 in START and END, and it switched to summertime. If I use 2016 in START and END it doesn't switch to summertime, so i reckon the year you enter (twice) is the year it starts recurring?

So display clock yields:

] display clock

16:06:11 CEST Wed 08/20/2014

Time Zone : CET add 01:00:00

Summer-Time : CEST repeating 02:00:00 2000 March last Sunday 02:00:00 2000 October last Sunday 01:00:00

Doing the same on a comware 7 platform (in this case a HP5900) yields

]display clock

16:07:16 CEST Wed 08/20/2014

Time Zone : CET add 01:00:00

Summer Time : CEST 02:00:00 March last Sunday 02:00:00 October last Sunday 01:00:00

This output reflects the configuration. Here the "repeating" keyword is missing and no year in the START and END times, which is how it "should be" - because "one-off" makes no sense,  and year-info in recurring summertime - makes no sense.

I guess they fixed it in Comware 7,and  I suppose fixing comware 5 is awful with backwards compatebility and tons of old configurations, but still ...

Regards (I'm not sure if asked a question)

I have no idea :-)

But this is what im currently using in both 5820 and 5120EI, it seems to went fine going winter->summertime. Now lets see how it behaves this autumn going back to wintertime =)

clock timezone CET add 01:00:00
clock summer-time CEST repeating 02:00:00 2000 March last Sunday 02:00:00 2000 October last Sunday  01:00:00

Edit:

Output from display clock:

23:20:03 CEST Thu 08/21/2014
Time Zone : CET add 01:00:00
Summer-Time : CEST repeating 02:00:00 2000 March last Sunday 02:00:00 2000 October last Sunday  01:00:00

@sdide
@Apachez-

Thanks a lot for sharing your exact "CEST repeating"-command. Saved me a lot of time and research.
I am currently configuring it on a V1910 (JE006A) but i guess as the OS is more or less the same, it will work.

Isn't that already possible through Web GUI of JE006A too?

I mean setting the correct Switch's Time Zone and then properly configuring related Daylight Saving Time parameters (DST repeats every Year, if you want).

I use HPE 1910 CMW520-R1519P03 (October 2017) firmware.

Hi,

I have HP Comware Software Version 7 and i want to configure its clock manually without the summertime or daylight savings.

So the output if I check the clock after the configuration should be only like this:

16:07:16 CEST Wed 08/20/2014

Thanks.
