This has been implemented in glibc 2.40 via:

commit 5361ad3910c257bc327567be76fde532ed238e42

    login: Use unsigned 32-bit types for seconds-since-epoch

    These fields store timestamps when the system was running.  No Linux
    systems existed before 1970, so these values are unused.  Switching
    to unsigned types allows continued use of the existing struct layouts
    beyond the year 2038.

    The intent is to give distributions more time to switch to improved
    interfaces that also avoid locking/data corruption issues.
