Raju, the way timestamps are rendered is controlled by Localization Tables. Navigate to the Localization Tables section and open the Default table. The token 'dateTimeFormat_Default' controls how time is rendered. The default value is 'yyyy-MM-dd HH:mm:ss.SSS'. If you change that to 'yyyy-MM-dd HH:mm:ssA', it will display your time with AM/PM.
Thanks Ravi. It's working.
But In my application datetime needs render in different formats in different places . So any way to handle in code level ?
I don't think you can; unless you use different languages. You could have the default language with the default timestamps and language1 with AM/PM and show that specific language depending on which user logs in.
