How often do you see the time zone next to the date of an article on news sites?

Not every reader would know that The Telegraph is in England so GMT. http://www.telegraph.co.uk/sport/tennis/mariasharapova/12186863/Maria-Sharapova-fails-drugs-test-at-Australian-Open-live.html
This article is from today Monday March 7/2016 but the date shows tomorrow’s date. At least a future date will make you think. But if it were the reverse, the information would be inaccurate, it wasn’t yesterday’s news it is today’s.
