Can you please tell me when you are planning to work on this? - I am currently programming https://www.elstel.org/atea/ and of course I would have liked to make the program time64_t fit without having to access kernel sources and without having to implement time64_t2char* conversion myself. The time implementation of libopenssl is also 32bit but it has a wraparound so that proper ASN-time usage will be possible after 2038. - And what about all the 32bit SoC computers like the Raspberry Pi? They also run Linux!!

It is on 2.34 plan [1], Carlos O'Donnel is reviewing it.  Similar to LFS,
you will need a newer flag to actually enable it (-D_TIME_BITS=64). 

The intended work for 2.34 still misses some ABI (utmp, utmpx, and lastlogin)
and installed programs would still use 32-bit; but it should enable
programs to proper support 64-bit.
