Another way could be using requirements.
Make a dummy unit. Find your spell in object editor and in the "Techtree - Requirements" add that dummy unit.

Then, when someone chooses this hero (whose abilities you want to limit by time of day) you create that dummy unit in map.
Then use simple trigger: When in-game time of day is "your desired night time", change owner of that dummy unit to owner of the hero.
When time becomes "your desired day time", you change owner of dummy to neutral passive.

This will disable hero's ability, as long as that dummy is not controlled by same player as hero.

Example: I named this dummy unit "Night time" and did exactly what I wrote above.
So when it's day time and I hover over that hero's ability (e.g. Sleep), it will be disabled with this written in it:
Requires:
- Night time
Note that the Night time written there is actually the name of the dummy unit

I used this technique to limit Dreadlord's Sleep ability. Look at hidden pic:

Why cant the dummy be created in map initialization?

 

[Nichilus]

You can create it whenever you want. But you would have to create one for each player at map initialization, since you don't know which player will pick that hero.

However if you create one for the player who picked that hero, you will end up with equal number of dummies to number of those heroes.

It's all about number of created dummies, there is no other reason.
Of course, the above is assuming you can have multiple of those heroes, not only one per map.

 

[Foxace]

Both should be able to play the same hero.

add a timer that follows 12h or check the time. When the timer expires then add ability to the unit,reset the timer, and remove it after next 12h thats also a solution

 

[Nichilus]

why use custom timer, when there is already a "game-time of day" timer?

 

[Adiktuz]

also, what if you cannot opt to remove the ability? like if it's a hero ability for example... removing it simply removes it's levels...

+ you won't see the skill (for non-hero) on the UI if you remove it

 

[stan0033]

there is GUI trigger "increase/decrease level of ability"

 

[Rheiko]

store its level before removing, then set the ability's level to the last stored level

The option Nichilus suggested is the best one, to use dummy units with the techtree requirements and to use the trigger to hide those units deppending on the ingame time and not a fixed timer. Removing the ability might confuse some players and it is much simpler to have dummy units hidden in some corner of the map than to remove abilities, store levels and then restore abilities and those same levels.
