Timezone name issue

[Revolve17x]

Hello!

I have a cisco 2921 router with 15.4(3)M7 ios software.

I made an update from ios 15.3 few days ago, and today I find out that timezone was reset.

I try to name timezone GMT+5 and router returns the error:

router(config)#clock timezone GMT+5 5 0
Apr 25 19:11:33.818: %SYS-3-TIMEZONE_INVALID: Invalid timezone name

In routers with 15.3 this problem does not exist. I do not find any bugs and release notes about timezone naming changes. Maybe someone encountered this problem too.

It's critical to set timezone name to GMT+5 because I use CDR parse software and do not have source code for change it variables.

 - Recursively check the helper  output of the 'clock ?' and 'clock timezone ?' commands , perhaps the syntax was changed.

Hi

As Marce mentioned  previosly, try to use clock timezone, for example:

Router(config)#clock timezone CST -5  and press enter.

Also check the space between GMT and +5

Also use the following command to align the logs with your time:

service timestamps log datetime localtime msec

Please dont forget to rate the comment if it is useful

Hi Julio

I mean than in ios 15.3 devices I can set Router(config)#clock timezone GMT+5 5 0 at example, where GMT+5 it's zone name nor offset. But in 15.4, when I try to set same name I'm get a syntax error.

It's not critical for network functionality, but this parameter used in third-party software we use to get a call statistics, and it was unexpected syntax change.
