Error in comparing two std::chrono::time_point instances

I have two std::chrono::time_point instances in variables exp and time. exp has a time in the future and time is the current time. But when I compare them as in this snippet:

std::time_t t_exp = std::chrono::system_clock::to_time_t(exp);
std::time_t t_time = std::chrono::system_clock::to_time_t(time);
std::cout << std::ctime(&t_exp) << std::ctime(&t_time) << (time > exp) << std::endl;

I get output:

Sat Apr 26 01:39:43 4758
Fri May 29 18:11:59 2020
1

Which is wrong because exp is in the year 4758 and time is in the year 2020.

Where am I going wrong?
