Timestamp mismatch in Jenkins Maven project - maven

Question

I am using Jenkins version of 2.289.3. And I am working on a Maven-TestNG Selenium project in it. I have added Build Timestamp plugin and setup it in Manage Jenkins -> Configure System -> Build Timestamp with a pattern yyyy.MM.dd.HH.mm.ss of Asia/Calcutta. I am using Publish Html reports in Post Build action of that job's configuration. I have given path for HTML directory to archive is:
test-output\reports\report_${BUILD_TIMESTAMP}
But when running this job, the time stamp is not matching for publishing html report. End-portion of my comsole output is given below:
ChromeDriver was started successfully.

Here the Chrome browser started at 4.55 but at post build action directory is created with timestamp containing 4.54. Why it is not taking the finishing time of the test? I can see a report folder generated at jenkins workspace is:
report_2021.08.03.16.55.36
Even I deleted the seconds from the time pattern, it is not matching with the generated report name. How can i fix this? Can anyone help me...Thanks in advance.

In my opinion the most probable explanation is as follows:
Build Timestamp plugin:
Export build timestamps to build env variables.
This is similar to setting environment variables via build parameters and the inline help of ☑ This project is parameterized reads:
Parameters allow you to prompt users for one or more inputs that will be passed into a build.
„passed into a build“ means that the environment variable is set before the first build step starts.
The output of a Freestyle test project with the following Execute Windows batch command build step confirms this (Timestamp plugin pattern is set to HH:mm:ss,S):
#echo off
echo Build step begin: %time%
:: let 10 seconds pass
ping -n 10 localhost > nul
echo Build step end: %time%
echo Build Timestamp: %BUILD_TIMESTAMP%
Console Output:
...
Build step begin: 21:19:33,88
Build step end: 21:19:42,90
Build Timestamp: 21:19:33,828
...
