特朗普正式成为美国总统的时间是1月20日当地时间中午12点，也就是格林尼治标准时间下午5点。

On Friday, Donald Trump will be sworn in as the 45th president of the United States. If you're a student of history (or just a fan of 3 Doors Down and Toby Keith), there are plenty of ways to watch the inauguration ceremony, parade and other related events online.

The major news outlets will have live streams on their websites, and you'll also be able to tune into live coverage on Twitter and YouTube -- no cable subscription needed.
