Change time zone setting
It's important to choose the right time zone for your blog, so that your posts appear with the correct dates and times. Also, if your time zone is incorrect, Blogger may think some posts are dated in the future, in which case they wouldn't be published.
You can change the time zone of your blog by going to the Settings | Language and formatting tab, and changing the setting for Time Zone under the "Formatting" section. Choose the correct option from the list, and click the orange button at the top to save your settings.
