SNTP Setting

I guess I should have done this long ago. A lot of network devices like HP switches have SNTP setting:

1) It will not accept a FQDN. It must be an IP address. I like time.windows.com but I have pinged it twice today and it has been a different IP every time I ping it. That doesn't make me feel real warm and fuzzy about using time.windows.com. Is there a more "standard" time server that everyone uses where the IP address will never change?

2) When setting up Daylight Savings Time the start and finish is easy enough but then it asks for an "offset" in minutes. What is this "offset"? Is it somehow like what ever UTC is? Where to I find this Offset? If it helps I am EST.

LD32,
I used to use tick.usno.navy.mil in my day.   Give that a shot   192.5.41.40

The "offset" for EST is -05:00.  If you need to enter in minutes that would be 300.  You can find all the UTC offsets a couple of ways.  I usually just go to my clock and go in to set the time zone but you can also find several places on the internet that list them.

On an HP switch you can set up Daylight Savings Time with these instructions:

HP is another company that has gone to the dogs. I got the manual on their switch (J9450A) and their "offset" is the amount of minutes to advance the clock during daylight savings time. It has to be a positive number. I did assume that the number you say in the time zone was the UTC but there is no place in the firmware to enter that.

   Got it all set up. The current time is 11:28am. The switch says it is  3:28pm. Leave it to HP. So it says the time is syncing with the SNTP server. Any idea why it is 4 hours off? Would the time server I am using make a difference?

Try this:

time timezone -300
time daylight-time-rule Continental-US-and-Canada
sntp server 0.0.0.0
timesync sntp
sntp unicast

Put in the IP of the time server where the 0.0.0.0 is.

I don't have those options in the switch. I have to pick a time zone from a drop down list. There is no daylight time rule. It is determined from setting the week and sunday it starts and end. It is mandatory sntp (no other option) and no unicast option.
Steven CarnahanNetwork ManagerCommented:
What switch model do you have?
LockDown32OwnerAuthor Commented:
It's a J9450A (V1810 24-port). I am going to open a case with them but any help you could give would be great.
Steven CarnahanNetwork ManagerCommented:
Okay,  I don't have one of those but according to the manual:

Offset The time amount of time in minutes to advance the clock during Daylight Savings Time.

The manual can be found at:  http://h20565.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c02563753&lang=en-us&cc=us

Look at the clock setting section (2 I believe - I found the above on page 2-11 and 2-12)

I downloaded the manual hours ago and had it set to per the manual. Your going to love this. Right there on the SNTP page it tells you the last sync status and the current time. It was successful but four hours off until.... I returned to the home page and it says "Time Source: NTP" and the time is absolutely perfect. I go back to the NTP page and the time is four hours off.

   This is HP and how they have gone to hell. I just purchased two new, hot off the shelf 1620 switches. No place to set a gateway address. I called HP and after 3 or 4 days the final response was "These are low end switches (only $200). There is no place to set the gateway. That is the way they were designed.". So it renders the SNTP, logs (which won't be time stamped right) and the internet diagnostics all moot because you can't set the gateway address.

   Three weeks later I by two of their $1,000 1920 switches and guess what? No place to set the gateway address. After a week I finally get them to escalate the case to tier two and the tier two tech figures out a way to set the gateway via telnet but.... they forgot the daylight savings time setting all together. Oops!

   So I go back to the 1620 thinking I can set the gateway via telnet and they forgot to add telnet to the 1620! Oops! They have just been one big disaster after another for the last three years. A total waste. I can't say enough bad things about them.

I have used Dell in the past but we moved to Cisco several years ago so I don't have a lot of experience with them anymore.

Back to the time issue.  I am trying to put this together in my head but it seems that the NTP page is actually showing the GMT time and the offset doesn't apply on that page?

I thing the problem has been resolved. If you look on the switch in the NTP settings it is 4 hours off but if you look on the switch in the home page the time is correct. That's what I mean about HP. Why would they display two different "current times" ???

They are idiots. Thanks for the help.
