I want to show a compare the timezone of a user with the timezone he has set in his CRM setting, and need to show the result in a pop-up; all this when the user logs in to CRM. Ours in a CRM 2011 On Premise Version. I tried following two options but didnt work out:
1. Added an iframe on a dashboard and added a JS file inside it.
2. Added a button on dashboard application ribbon and tried using enable rule and display rule in order to show the popup.
Can anyone please suggest me how to achieve my requirement?
