Thanks for respond,

I am using NTP reference server, but I can't see DTS option to configure in CUCM. can you please show me how to access to DTS?

what DST option??????

if you're still thinking on windows versions and the checkbox, drop that idea, this is linux



if this helps, please rate

Ok, it doesn't calculate DTS automaticall, then I had to change timezone to show correct time.

any suggestion would be appreciated.

Actually Java was helping a lot before, but I don't know about this time. Actually DST in CUCM linux based has a bug based on Cisco TAC engineers.

and i do try to help people as this is completely separate from what my role job is and do it on my own free time, i apologize if you feel it's rude but there are many things that simply are not going to be the same.

in windows you had the time settings and the DST checkbox, linux is never going to have that. you simply need to understand that many old ideas you had on windows you'll have to forget because linux doesn't have that.

if i hurt your feelings i apologize, i didn't mean to

We here at cisco we really apologize for all this DST inconvience, i know you need more than our apologies, the way DST works in Linux is different.

We discovered a DDTS which is in the thread Michael posted above, you will have more information there.

In regards java response, please feel free to contact me directly for any questions in regards DST gogasca at, im out of the office but still replying emails.

I would like to confirm, whether do we have to make any changes in DST, or it shall be done automatically ?

If we need to change it manually, then i understand we need to change following parameters

1.  Time of day Routing: Time Period ,Time Schedule, Partition, CSS also ?

2.  Date/Time Group

3.  Device Pool

We are using CUCM v6.1.2.1000-13
