But how must this conversation be correct???
- Excuse me, what's the time?
- It's about six o'clock.
etc.
The problem is that usual Englishman just wouldn't understand you if you speak this way. But for Russian people this seems quite normal and understandable

For example the phrase "rain pour like from a bucket" they tell "it rains cats and dogs".
Actually, this phrase is a good example of English idiom but it is used in England really seldom. It would be better to say that there is quite heavy rain outside or something like that

O God of Earth and Altar,
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
