Here is the call graph for this function:

time_delta_to_str_int64_min()

static void time_delta_to_str_int64_min ( void  )

static

Format the most negative delta possible.

fr_time_delta_to_str() takes the magnitude of the delta with a MOD()
macro.  INT64_MIN is the awkward case: negating it in a signed type is
undefined (its positive counterpart, 2^63, isn't representable in
int64_t), so the magnitude has to be taken in the unsigned domain.
This checks the boundary formats correctly rather than tripping UBSan.
