I guess its cropping the high order bits? So millis > comparisons might work but timestamps generated from this value might not? Yes, this is intentional. The ngx_current_msec variable (and the ngx_msec_t type) is to be used to effectively implement timers, and hence it uses platform-specific fast integer. As such, it can easily overflow on 32-bit platforms.
