- [Voiceover] In the last movie, we saw how to add…the offset from UTC to the time zones option list.…In this movie, we'll improve the formatting…of those offset values.…So what we've already done is,…we used the DateTime object to get the offset…and divided it by 3600, and then we displayed it to the user…and it looks something like this.…What we don't like is the fact that this says minus four…and this says one and two and so on.…It doesn't really give us a time.…It doesn't feel like it's a time.…In fact, here, it's not even really clear what this is.…
UTC/GMT one.…What does that mean?…That's not the way that we usually see these represented.…So we need to do some formatting here.…And there are a couple of ways that we could do that.…The first is that we could add…a new function called…function format_hours_minutes.…We'll pass in a float to that.…And then in there we could actually just do the formatting…that we need.…We can take that float apart.…We can use floor to find out what the integer portion is.…
That'll give us the hours.…
