I do not see the issue with a linux build. I think it might be associated with
#define CFE_PLATFORM_TIME_CFG_BIGENDIAN
The default is to #undef CFE_PLATFORM_TIME_CFG_BIGENDIAN - makes sense on linux/x86
But for vxworks/SPARC, I would think it should be defined.
"** If this configuration parameter is defined, the CFE time server will
** publish time tones with payloads in big-endian order, and time clients
** will expect the tones to be in big-endian order. "

vxworks/sparc will build if
#undef CFE_PLATFORM_TIME_CFG_BIGENDIAN
