I'm afraid Recursive Strike would be extremely breakable and over-powered as written. Also, it would lead to jukes that would make LeBlanc look like a fool.

I dunno how I feel about Chronospheres, what would the area of the circle they dropped over? I'd almost like it to be an ult where he places a globe that heals allies and deals damage to enemies who enter over time. Failing that, maybe a spell where he places one rune with a delay on activation;high damage or healing but requires leading of the target or good communication.

Actually, Time Warp is perfect, I love that. Seriously try to get that to Riot's attention.

Space-time Schism is kinda wacky, I could imagine it being an ult where enemy Champions struck take damage and a push aside, but rather than knocking them back make it impassible terrain for enemies (but not allies). That would play up the instance where Zilean puts the entire Crystal Scar in stasis with the League's help. I cannot imagine it as written with any sort of damage. AoE knockback/scatter from mage range is devestating.

I think the first Rewind is better than the second. To be honest, I don't like either of them though. Zilean with a selfish ult would be somewhat strange I feel, though I concede it would feel very lore-filled for him to just pop back up.

So, let me take a crack at Zilean borrowing a few of your, admittedly, awesome ideas.

Rewind (Passive) Passive: Zilean gains double effect from cooldown reduction to the cap of 40%. (Trying to think of a good passive for the Chronomancer is not an easy feat at all. This is admittedly very much yoinked from Yasuo but I think themematically it fits Zilean as the master of time without sacrificing an entire ability to showcase that one aspect of his character. This make for super fast and easy CDR cap while giving him some early power.)

Twisted Time (Cooldown: 10) Active; First Cast: Zilean summons a space of twisted time that lingers for up to three seconds. Active; Second Cast: Zilean detonates the area enemies caught within the area suffer damage while allies are healed. (I view that as the replacement for Time Bomb; Zilean strikes me as the type of character archtype that best controls space but also has to lose something to gain. To heal his allies he sacrifices the ability to harass his foes, and vice versa. Of course, if you manage a really good cast in teamfights it could be a real game changer.)

Time Warp (Cooldown: 20) Active: Zilean hastes or slows the target champion for 3.5 seconds, depending on whether they are allied or enemy. For the duration, the target leaves behind a trail that hastes or slows champions who move within it. (Dude, this is amazing and perfect. This is exactly the ideal I would see in Zilean's rework. You are spot on like no tomorrow here.)

Delay Doom (Cooldown: ???) Active: Zilean marks an allied champion for ? seconds, the marked champion receives 80%/75%/70%/65%/60% of damge taken upfront and the rest as a DoT over 1/2/3/4/5 seconds. (Okay, this is a little wonky I admit that, but I think it would be interesting instead of 'support with shield'. The idea is to give a key member of your team those few extra seconds to survive without pushing the skill into Ult level territory. It combos well with shields, regen, and potions, and makes tanks even tankier ideally.)

Spacetime Schism (Cooldown: ???) Active: Zilean twists and seals an area of space for 3.5 seconds, dealing massive damage to enemies caught within and rendering it impassible to enemy champions. Enemy champions are pushed to the nearest edge of the zone. (This, to me at least, defines a positioning spell and as an ult I thought it would be okay to allow your team to move through the area; potential problems though quickly arise if your entire team is suddenly unreachable in a buble and can rain death on your enemies so perhaps rendering it entirely sealed would be wiser.)
