Need help with Jython script for commenting on issue

[CCP TechOps]

I have button "Review" in Jira workflow with no screens. Whenever a manager reviews the issue he has to click on the Review button. Once this button is clicked jython script should automatically create comment like "Review performed by <user who clicked review> at <current time>.

I have written a jython script in post function however it does not work and give me errors. Below are the script and errors. Let me know where it went wrong and provide the correct syntax pls.

{code}

from com.atlassian.jira import ComponentAccessor

from com.atlassian.jira import ComponentManager

from com.atlassian.jira.util import ImportUtils

from com.atlassian.jira.issue.comments import CommentManager

from com.atlassian.jira.datetime import datetime

subTaskManager = ComponentManager.getInstance().getSubTaskManager()

commentManager = ComponentManager.getInstance().getCommentManager()

authenticationContext = ComponentManager.getInstance().getJiraAuthenticationContext()

currenttime = datetime.now()

comment = "Peer review performed by \"" + authenticationContext.getLoggedInUser().toString() + "\" at \"" + currenttime

commentManager.create(comment, True)

{code}

Errors:

root cause: Traceback (most recent call last): File "<string>", line 5, in <module> ImportError: cannot import name datetime

Try this one. Dont use componentmanager most of functions were deprecated.

from com.atlassian.jira.component import ComponentAccessor
from com.atlassian.jira.issue import Issue
from java.util import Calendar


ComponentAccessor=ComponentAccessor()
JiraAuthenticationContext=ComponentAccessor.getJiraAuthenticationContext()
LoggedUser=JiraAuthenticationContext.getUser()
Calendar = Calendar.getInstance();
Time=Calendar.getTime().toString()

comment = "Peer review performed by \"" + LoggedUser.toString() + "\" at \"" + Time
CommentManager=ComponentAccessor.getCommentManager()
CommentManager.create(issue, LoggedUser, comment, True)
