Depending on which version of EOSIO you use, there are different options available for finding the current time. What are they?

Until eosio.cdt v1.6

You could use:

  • eosio::current_time()
  • now()

From eosio.cdt v1.6 onwards

You have to #include <eosio/system.hpp> and then you can use:

  • eosio::current_time_point
  • eosio::current_block_time

    Where was this change mentioned, I don't see it in any release notes.

    I don't think they mentioned it directly. It was just something you had to find out for yourself. That is why I made a question and answered it, anticipating people having this problem. Apr 3, 2019 at 21:13

    thank you. I wish they would bloody document stuff like this so poor sods like me don't spend all kinds of hours trying to figure out why something doesn't work. question: I see in the 1.6.1 version of the CDT, that now() is still defined: github.com/EOSIO/eosio.cdt/blob/master/libraries/eosiolib/… however, if I #include <eosio/system.hpp> I still get the error "use of undeclared identifier 'now'; did you mean 'new'?" -- why is that and how do I fix it?

    and if I look in libraries/eosiolib/system.hpp, I don't see either current_time_point or current_block_time (I need to know the return types)... how does this work? I see that including from eosiolib is deprecated and we must include from eosio, but I don't see any such directory!

    and what the hell was wrong with providing now() anyway?? I'm so aggravated

In older version we can only get the current block time with publish_time(). But now its available also in eosio::current_time_point eosio::current_block_time. Hope this helps you.
