Namespace polution.  There is no "." in 144, so the reasoning is that
either time_t or ut_time is defined as a macro in a header file.
"time_t" is a pretty standard type, so it must be ut_time.

  grep ut_time /usr/include/*.h

gives:

/usr/include/utmpbits.h:# define ut_time        ut_tv.tv_sec

One solution would be to give "ut_time" a different name in those
structures.
