I'm in the midst of setting up an ISE server but I noticed something. The clock is syncing with our NTP server, but it apparently has no setting for Daylight Savings Time, so it is currently 1 hour behind the rest of our systems. Is this going to cause an issue and if so, how is it fixed? Thanks!

Can you please send me the following outputs from ISE command line interface :
1. Show version
2. Show running-config
3. Show timezone

I changed the timezone to America/New York and it looks to be working. Thanks!

How did you configure time zone?
I use 'Stockholm/Sweden' (or reverse) and get CEST/CET with that.

To set the system clock, use the
clock
command in the EXEC mode. To remove this function, use the
no
form of this command.
clock set [month day hh:min:ss yyyy]
Syntax Description
clock set | The command that sets the system clock. |
month | Current month of the year by name. Supports up to three alphabetic characters. For example, Jan for January. |
day | Current day (by date) of the month. Value = 0 to 31. Supports up to two numbers. |
hh:mm:ss | Current time in hours (24-hour format), minutes, and seconds. |

Wow, seriously? Changing the timezone renders the appliance unusable? That seems like a little it of a bug-like feature doesn't it?
How is one to change the timezone then? Perform a complete reinstall of the appliance?? What if it's a Standalone?

For the install we just did we configured it for EST time as per the requirement, now the clock is off by and hour. This must be a feature?

Cisco ISE currently automatically changes time for daylight savings time depending on how the timezone was configured via the CLI. Please see the following link for sample time zones:http://www.cisco.com/en/US/docs/security/ise/1.1/cli_ref_guide/ise_cli_app_a.html#wp1013028

Actually, selecting simple EST does not adjust automatically for Daylight Savings Time (DST) and this is why I had to change the timezone to specify a city (even though to my knowledge, there is no state in the EST timezone which does not also participate in DST).
Now someone mentions that changing the timezone breaks the appliance. If this is true, it's possibly the least robust solution I've seen from Cisco in years.

This is straight from TAC on what we need to do to correct the problem. I doubt we will push this remediation forward after this.
So the timezone itself is probably actually in EST (Eastern Standard Time), but this does not shift for daylight savings.
You will want yours to actually be EST5EDT to execute daylight savings (EDT).
I can provide you the process in which to change the timezone, but we do not recommend changing the timezone. Changing it may cause database errors. I have seen many systems work perfectly fine, but a couple that have corrupt due to the change. This is simply a warning.
Attached is the procedure.
Step 3 is actually where the change in the config happens.
In step 4, you will see the application reset-config ise. This will wipe your box to factory defaults.
A few customer were able to simply 'reload' (reboot) the box and the change took place with no ill side affects and no need to restore backups.
Again, we do not recommend changing the timezone, but the choice is yours.
