file generated
test\ct_test.c(503): warning C4244: 'initializing': conversion from 
'uint64_t' to 'const time_t', possible loss of data


Probably triggered by the usage of:

-D_USE_32BIT_TIME_T


I use that define for 32-bit builds on my 64-bit hardware as per this 
old post:

Casting to time_t appears to correct the issue and the build completes 
successfully:

     const time_t default_time = 
(time_t)CT_POLICY_EVAL_CTX_get_time(ct_policy_ctx) /
                                 1000;
