What does "it" mean in the sentence "What time is it?"?
463387
In this case the word "it" is called an expletive. Syntactic expletives are words that perform a syntactic role but contribute nothing to meaning. Expletive subjects are part of the grammar of many languages such as English, whose clauses normally require overt provision of subject even when the subject can be inferred. \nWhat this means is that English needs a  both a subject and a predicate to make a complete sentence and "it" only fills the place of the subject to follow a structure.

Generally, it means, something like "Isn't it obvious?" \n\n"To be able to tell" something means that you have enough information to understand something.  If it's a question, it's usually meant somewhat sarcastically.  So, if it's a question, the asker is usually surprised that something isn't obvious to you, because it might be obvious to other people.

BLONDE: "Excuse me, what time is it right now?"\n\nWOMAN: "It's 11:25PM."\n\nBLONDE: (confused look on face) "You know, it's the weirdest thing, I've asked that question thirty times today, and every time someone gives me a different answer."

He threw the ball.\nIs the ball there?\nIt was their ball.\n\nWhat is the difference between its and it's?\n\nIts is the possessive form of it. It's is a contraction of it is or it has.\n\nExamples: \n\nIt's a common mistake.\nThe boat has a hole in its hull. \nThe confusion arises from the dual function of the 's ending, which can indicate either possession or contraction, as in: Joe's hamburgers are the best (="The hamburgers which are Joe's — that is, in that he makes them — are the best"); Joe's going to have to buy some more patties soon (="Joe is going to have to buy some more patties soon"). However, 's is never used to indicate possession in pronouns. We do not write hi's (instead of his), for example. \n\nHere is a test we can perform to determine whether to use it's or its: Replace it with his and see if the sentence still makes (grammatical) sense. His a common mistake does not make sense. The boat has a hole in his hull does make sense — at least grammatically; of course boats are not boys, but we can pretend that they are for the sake of improving our spelling. The rule we shall apply, then, is this: If the sentence makes sense with his, which does not have an apostrophe, it is safe to replace it with its, which also does not have an apostrophe.

What time will your plane arrive? (Asks future tense, not present perfect - basically its the only one that sounds normal.)\nBy the time he comes home, I will have finished dinner. (Tense is correct.  Specifies event passed not event occuring)\nHe can predict how many people will be living in these regions.  (Can predict specifies indefinite future)\nThey will soon be able to solve the problems. (The other one simply does not make sense.)\nAccording to the timetable, the plane arrives at 7PM (For all I've been taught you want to avoid wordiness and to be verbs.  I'm honestly not really sure on this one.)

"Seven minutes past" is short for "Seven minutes past the hour" or seven minutes after the last "o'clock" e.g. it's 10:30, someone asks, "At what time did we come in?"  you say, "About seven minutes past."  means you came in about 10:07.

The other two answers were correct, however, to be more specific: #1) is person, #2) is place, and #3) is to time.\n\n1. Do they know who they are? Full name.\n2. Do they know where they are at, at the present time? the hospital, or perhaps the city.\n3. Do they know what time it is? the exact or approximate time, part of the day, and morning, day, or night.\n\nIn addition, there is a #4) the date, which speaks for itself.

Normally, "time flies" is a phrase where 'time' is the noun, and 'flies' is the verb - meaning that time moves quickly.\n\nHere, however, 'time' is the verb (like what you use a watch for during a race) and 'flies' is the noun (like the pesky insect).  Thus, it's saying: we can't say how fast flies are flying - they're going too fast.\n\nMildly funny at best, but there you go.

It is impossible to know without the context. What's the whole sentence you find the phrase in?\n\nEdit: That really makes no sense. It's certainly not a frequently used abbreviation. Some more information would really be helpful.

Einstein said we are living in the past time, that means we have not "now time"!\nSo, nobody can not answer, what time is it! maybe we can ask, what time was it!!
