Time flies like an arrow.  Fruit flies like a banana.

Posting from Ontario today - I'm currently sitting on the patio  of the Delta Chelsea hotel, located near Yonge and College in downtown  Toronto.  It's a beautiful sunny day, and although the hotel wants to  charge the ridiculous daily fee of $13.95 for hardwired internet access  in the rooms, they have free wireless downstairs.  Unlike the various  dullards who are crammed onto every available flat surface in the lobby,  I noticed that there was this outdoor section near the food court  area....hmmm....so here I sit typing away outdoors in a shady spot with a  nice little breeze, pleasantly isolated from the hustle and bustle of  Yonge Street, sipping a frigid iced tea between sentences.
It's  interesting to visit a familiar city on a semi-regular basis of about  twice a year.  It's a bit like slow time travel - changes can be large  and noticeable, or small and subtle.  In fact, this is probably the only  feasible method of time travel, although it's not exactly what most  people have in mind when they discuss the concept.
When  you think about it, all you really need for successful time travel is a  reliable method of suspended animation* and a great deal of faith in  either automatic timing systems or your fellow man.  Want to move to the  year 3010?  Climb in, close the lid, slowly drift off to sleep....when  you wake up, presto, 1,000 years in the future.
As with most of the basic science fiction concepts, this one is first introduced by H. G. Wells. In his 1910 novel 
The Sleeper Awakes**,  his character falls into a mysterious trance rather than being put on  ice, but the results are the same.  Most of the novel is the sort of  thinly veiled socio-political criticism that too often dominates Wells'  writing, but it does offer the interesting idea that after sufficient  time, a person in suspended animation whose financial life continues to  be active would eventually possess all the money in the world. (In the "A Fishful of Dollars" episode of 
Futurama, Philip J. Fry proves the benefits of compound interest by unintentionally leaving 93 cents in his bank account for 1,000 years at 2.25% and ending up with over four billion dollars.)
The idea was continued by Robert A. Heinlein in his 1956 work 
The Door Into Summer,  which amplifies on the problems faced by Wells' protagonist in terms of  adapting to a completely different society in the future.  Obviously all of the  scientific knowledge possessed by Heinlein's inventor/hero is obsolete, but the  deeper problem is that 
all of his knowledge is obsolete, in every aspect of life.
They  brought me modern clothes right after breakfast the next morning...and I  had to have help in dressing. They were not so odd in themselves  (although I had never worn cerise trousers with bell bottoms before) but  I could not manage the fastenings without coaching. I suppose my  grandfather might have had the same trouble with zippers if he had not  been led into them gradually. It was the Sticktite closure seams, of  course-I thought I was going to have to hire a little boy to help me go  to the bathroom before I got it through my head that the  pressure-sensitive adhesion was axially polarized. Then I almost lost my  pants when I tried to ease the waistband. No one laughed at me.
By the way, the hidden joke is that this particular Sleeper has ended up in the distant future of the year 2000.
When  I mentioned that faith in one's fellow man was required for Sleeper  time travel, it's not only in the area of having someone wake you up.   Larry Niven's story 
The Defenseless Dead combines a growing need  for transplant donors with a large pool of "corpsicles" - people in  cryogenic suspension.  The result?  The Freezer Laws, which decree that  anyone without sufficient funds to support them upon awakening is  officially dead and as such can be used as a source of spare organs.  In  other words, you still wake up, but "one piece at a time", as one of  the characters comments.
In my opinion, the best use of the idea of stasis time travel has to be Vernor Vinge's clever 
Marooned in Realtime,  a murder mystery disguised as a science fiction novel, or vice versa.   Vinge's novel is based on the idea of bubbles of suspended time -  "bobbles", in the parlance of the novel.  Bobbles are indestructible and  with sufficient power can be created to be of almost any size or  duration.
The novel takes place after the Singularity, a  point in human development where humanity has made a quantum leap to  another state of evolution, leaving behind a silent, empty planet.   However, people who are in bobbles suffer the fate of the lame boy in  the Pied Piper legend, left behind when the doors to paradise close.   The more technologically advanced survivors decide to use their bobbling  technology to travel through however many millenia are necessary to collect  all of the remaining humans as they emerge from their bobbles, in hopes  of rebooting humanity as a species.
Problems arise when  one of the originators of this plan is murdered.  The weapon?  Old age -  they're trapped outside the bobbles and left to die while everyone else  travels a thousand years.  Needless to say, the clues are not in the  best of condition after the crime is discovered.
Of  course, interesting though all of these ideas are, there's one problem  with this particular approach to time travel.  After all, once I've  finished my little faux time travel visits to Toronto, I can go home  again...

*   Just for the record: regarding my own personal time travel visits to  Toronto, I do not consider living in Vancouver to be the equivalent of  suspended animation.
** Originally published in 1899 under the title 
When the Sleeper Wakes,  but Wells did some rewriting and re-published it - which may mean  that Wells also originated the concept of the director's cut.
