Is the uptime (in /proc/uptime) also 0? Most Raspberry Pi's are delivered without RTC and /proc/stat btime is set to '...the time read off the RTC. This is represented in Unix time (aka POSIX time or Epoch time).' (see [1]) and so will always be '0' (until you change the date per cmdline or ntp)... The htop misleading error message is fixed upstream by [2] and the current version used on buildroot git master (htop-3.1.1) already contains the fix...
