I've thought about this phrase before after hearing it quoted by friends. (I never actually knew it was a song lyric, let alone which song it was from.) I always thought about it in terms of local time, as opposed to zone time.
The lyrics do state that it is July, but not what year it is. According to Wikipedia "By about 1900, almost all time on Earth was in the form of standard time zones, only some of which used an hourly offset from GMT. Many applied the time at a local astronomical observatory to an entire country, without any reference to GMT. It took many decades before all time on Earth was in the form of time zones referred to some "standard offset" from GMT/UTC."
The song also mentions a drink called a "Hurricane". This drink appears to have been invented sometime in the 1940s. So, I think it possible that is a wider range of areas where this time difference could have occured.
Of course, like I originally stated: if you go by local time even now, it is always five o'clock somewhere. :)
