Yes. I can think of two (only one correct) possible meanings, though, depending on the usage: The complete sentence, "Fall's planting time" means, "The season of Fall is the time of year when we plant." This is not correct! Fall's shows possession , no conjunctions includ the word "is". You could also say something like this: "Late September is Fall's planting time," meaning: "The time within the season of Fall when we plant is late September."
No, the sentence is not grammatically correct. It should be: "It had been a long time since I had written to you."
As time flies is grammatically correct.
no.
"It is the time for someone" is correct. It implies that it is the right moment or opportunity for that person.
It can be, but not all the time.
yes
No, I think the correct way is- Is this the first time you've seen it?
Yes, both "joyful time" and "joyous time" are grammatically correct and can be used interchangeably to convey a time filled with joy and happiness.
That sentence is grammatically correct.
Yes, the phrase "I came home at about one o'clock" is grammatically correct. It follows a subject-verb-object structure and conveys a clear message about the time of arrival.
Unless you hurry, you will not be able to reach school in time.
Yes, but whether it means anything is unclear. A sentence may be grammatically correct and total gibberish at the same time.
