Hi List, I think Haiku have this problem too: http://en.wikipedia.org/wiki/Year_2038_problem What can a good way to fix this and where all need this? - libroot? - libbe? - POSIX time.h (posix and posix/sys) vs Haiku bigtime_t (support/SupportDefs.h) and Kernel Time (kernel/OS.h) - BeFS ? but the FS are 64 bit. I look into posix/time.h it little bit old (some other POSIX stuff too) then posix/sys/time.h (and why have we the double headers of time.h?) It's nice when found some developers he can review and fix this. What think the list about this problem? stargater
