Interesting stuff. The only thing I've ever heard about time control is the entity Fotamecus. I'm not entirely sure this story is true but I feel like I've had some success with time control.
Supposedly there is an entity named Fotamecus, that can expand (slow) and compress (hasten) time whenever you need it. His original creator calls him a viral egregore- he started out as a mantra, then a sigil, servitor, and made the jump to egregore. This is basically how the creator Fenwick Rysen describes the entities creation. When he was a servitor his sigil was put on the internet and many people started working with him. Many different Fotamecus entities were created, and they work together as one entity. The reason for having so many different entities was because of the consequence of compressing or expanding time. Whenever time is compressed it expands afterward to balance out. I guess how it works is- if you want to expand time in the morning so you can sleep in, but don't want it to compress later in the day, you ask your Fotamecus to expand time, then petition another Fotamecus somewhere else to pass off the compression.
I haven't heard about more acute time control. This could all be in the mind and though, like self hypnosis. But you should definitely give Fotamecus a try if you're interested, I'm not very good at working with entities at the moment and stopped working with Fotamecus a while ago. I'd be very interested to hear the results if you give it a go. http://www.chaosmatrix.org/library/chaos/texts/fotamec1.htmlhttp://www.chaosmatrix.org/library/chaos/rites/fotamec3.htmlhttp://www.chaosmatrix.org/library/sseg.php
Time is one of those things that we really just don't know much about, there's definitely a lot of room for exploration.
Just a fact- did you know that the great pyramid of Giza actually slows down time at the base of it? It's so large that it slows time like a boulder sitting in a river. It's unnoticeable but it makes you wonder. Theoretically I suppose time might move faster on smaller planets, and slower on larger planets. This leads me to wonder if life could evolve on smaller planets faster than on larger planets
woo that was a long post
