    [ https://issues.apache.org/jira/browse/IGNITE-11177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16761756#comment-16761756

Vladimir Ozerov commented on IGNITE-11177:
------------------------------------------

We need to change data type all such columns to LONG, as this is not TIME, but rather duration.
And duration cannot be expressed in terms of TIME data type.

> This is because we are using TIME type for several additive measurements:
> {quote}SqlSystemViewNodeMetrics.class:
>                         valueTimeFromMillis(metrics.getTotalJobsExecutionTime()),
>                         valueTimeFromMillis(metrics.getTotalBusyTime()),
>                         valueTimeFromMillis(metrics.getTotalIdleTime()),{quote}
> which will be hundreds of hours on long-running cluster, but {{TIME}} type is limited
to 24 hours and will fail to be converted otherwise, as in:
> {quote}0: jdbc:ignite:thin://localhost> SELECT CAST('40:52:26.548' AS TIME);
> Error: Failed to parse query. Невозможно преобразование строки
"40:52:26.548" в тип "TIME"
> Cannot parse "TIME" constant "40:52:26.548"; SQL statement:
> SELECT CAST('40:52:26.548' AS TIME) [22007-197] (state=42000,code=1001){quote}
