is time_3 equivalent to 0 or 1 in such a expression correct?

"time_3=(t1<time()&&time()<t1+c1)||(t2<time()&&time()<t2+c1)||(t3<time()&&time()<t3+c1)||(t4<time()&&time()<t4+c1)||(t5<time()&&time()<t5+c1)||(t6<time()&&time()<t6+c1)||(t7<time()&&time()<t7+c1)||(t8<time()&&time()<t8+c1)||(t9<time()&&time()<t9+c1)||(t10<time()&&time()<t10+c1)||(t11<time()&&time()<t11+c1);"

but this error is shown:

Look at where the ^^^^^^^^^ points in the error message.

You need two "=", i.e. "==" to test for equality.

i want the time_3 become the result of conditions as a bolean value 0 or 1

[immortality]

any comment from dear Bernard?

[immortality]

i have not succeed yet.any idea?

[immortality]

i don't give it up at all.
It'll be nice to have some help on it.

Booleans can only be "true" or "false". Anyway. Instead of "time_3==true" (which I'm not sure whether it is implemented) you can just write "time_3" (which should work)
