+Subject: [PATCH] transaction: use system_clock::to_time_t for start time
+
+On i686, time_t is a 32-bit long, so deriving the start time via
+duration_cast<seconds>(now().time_since_epoch()).count() narrows the
+64-bit count and trips GCC 16's -Wconversion, failing the build under
+-Werror. system_clock::to_time_t() returns a time_t directly, so the
+narrowing is gone and the intent reads more clearly.
