Time In a Bottle Fix adds 4 new features:

Crop Acceleration
Animal Growth Acceleration
Cheater’s Time in a Bottle and extended duration, increase duration up to 240 seconds.
AE2 Acceleration. You can now accelerate Inscribers and other AE2 blocks

Tiab Fix is an addon and will not work without the Time in a Bottle mod installed.

Even though it existed in older versions, Time in a Bottle does not accelerate crops in modern versions.
This mod fixes that issue.

You can now accelerate crops again.

Crop acceleration

You can also accelerate animal growth.

No more waiting for baby chickens, cows, or sheep to grow up!
Animal Acceleration is also compatible with JADE. A tooltip will appear above the animal you’re accelerating.

Cheater’s Time in a Bottle

You could already add absurd amounts of time to Tiab via commands, but if you ever set the maximum Tiab speed to something like 4096x in the configs, you may have noticed that the time still runs out.
Cheater’s Time in a Bottle fixes this. You can get a Tiab with truly unlimited time.

As an extra feature, in Cheater’s Time in a Bottle you can also increase the duration by Shift + Left Click.
Previously, whether the speed was 16x or 256x, the duration was always 30 seconds. Not anymore.

You can now increase the duration up to 240 seconds.
(This is exclusive to Cheater’s Time in a Bottle.)

It can only be obtained via command:

/tiabfix unlimited
