When we load files by using Rational Team Concert SCM, we can now specify to use the timestamp from the file in the repository as the timestamp on disk.
In Eclipse client, this option is available in the Load wizard under Advanced section of the project or folder selection page (Refer to the attach Image1).

In CLI, we can enable the same using the parameter "--preserveTimestamps" with SCM load command.

But, the Jenkins build definition which is custom built doesn't have this feature enabled currently.
We need this feature available in the Jenkins Team-concert plugin (https://plugins.jenkins.io/teamconcert/).
This feature is helpful while we perform an incremental build (where only the changed files are compiled). We perform this type of builds very often.
we need this option under "Load Option" view of "Load components by using dynamic load rules" on Jenkins job configuration UI (Refer to the attach Image2).
