Hi compliments,
You asked if there are different "little whiles". I say it is apperently so. Simply because the scriptures you qouted from John are already fulfilled in the gospels itself. Jesus is talking about His death and resurrection and ascension. Some other versers (Like that hebrew verse) refer to the day of the Lord and the second coming of Jesus. Obviously these are not yet fulfilled and involve a much greater timespan than the little whiles in the gospels you quoted. So I think it is not impossible to know if there are different little whiles, only time can tell, and it did, right? :-)

here are some more scripture on the day of the Lord and the last days for if you are interested.
1 John 2:18 Little children, [b]it is[/b] the last time
Is 13:6 Howl ye; for [b]the day of the LORD is at hand;[/b] it shall come as a destruction from the Almighty. 7 Therefore shall all hands be faint, and every man's heart shall melt: be faint: or, fall down8 And they shall be afraid: pangs and sorrows shall take hold of them; they shall be in pain as a woman that travaileth: they shall be amazed one at another; their faces shall be as flames. be amazed: Heb. wonder one...: Heb. every man at his neighbour flames: Heb. faces of the flames9 Behold, the day of the LORD cometh, cruel both with wrath and fierce anger, to lay the land desolate: and he shall destroy the sinners thereof out of it. 10 For the stars of heaven and the constellations thereof shall not give their light: the sun shall be darkened in his going forth, and the moon shall not cause her light to shine. 11 And I will punish the world for their evil, and the wicked for their iniquity; and I will cause the arrogancy of the proud to cease, and will lay low the haughtiness of the terrible. 12 I will make a man more precious than fine gold; even a man than the golden wedge of Ophir. 13 Therefore I will shake the heavens, and the earth shall remove out of her place, in the wrath of the LORD of hosts, and in the day of his fierce anger.
Joel 2:1 Blow ye the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: [b]for the day of the LORD cometh, for it is nigh at hand;[/b] trumpet: or, cornet2 A day of darkness and of gloominess, a day of clouds and of thick darkness, as the morning spread upon the mountains: a great people and a strong; there hath not been ever the like, neither shall be any more after it, even to the years of many generations.
Zeph. 1:14 [b]The great day of the LORD is near, it is near, and hasteth greatly,[/b] even the voice of the day of the LORD: the mighty man shall cry there bitterly. 15 That day is a day of wrath, a day of trouble and distress, a day of wasteness and desolation, a day of darkness and gloominess, a day of clouds and thick darkness, 16 A day of the trumpet and alarm against the fenced cities, and against the high towers. 17 And I will bring distress upon men, that they shall walk like blind men, because they have sinned against the LORD: and their blood shall be poured out as dust, and their flesh as the dung. 18 Neither their silver nor their gold shall be able to deliver them in the day of the LORD'S wrath; but the whole land shall be devoured by the fire of his jealousy: for he shall make even a speedy riddance of all them that dwell in the land.
Rom 13:12 The night is far spent, [b]the day is at hand:[/b]
1 Peter 4:7 [b]But the end of all things is at hand:[/b] be ye therefore sober, and watch unto prayer.
8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
9 [b]The Lord is not slack concerning his promise, as some men count slackness;[/b] but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. 10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, 12 [b]Looking for and hasting unto the coming of the day of God,[/b] wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
Rev 22:10 And he saith unto me, Seal not the sayings of the prophecy of this book: for [b]the time is at hand.[/b]
12 And, behold, [b]I come quickly;[/b] and my reward is with me, to give every man according as his work shall be.
20 He which testifieth these things saith, [b]Surely I come quickly.[/b] Amen. Even so, come, Lord Jesus.
2 Th 2:2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, [b]as that the day of Christ is at hand.[/b]3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
2000 years after John penned down it was the last time, the time is definetly later. The day of the Lord is coming, it is still at hand and even nigher, Jesus is still coming quickly, eventhough it does not appear so after 2000 years have passed (2 days for the Lord (sorry compliments)). But remember that the Lord is not slack concerning his promise, neither do we need to be troubled and let no man decieve us that it is only a couple of days ahead and thus we can stop working. But we do need to be sober and prayerfully watch for the coming of the Lord. He will come the same way as he went, with the clouds.
(With eternity in mind, I think the day of the Lord is at hand from the fall, 6000 years is not that much, we're just like grass)
Blessings,
