Description
http://nginx.org/en/docs/syntax.html
According to the document above default time value for nginx.conf time values default to seconds when a time suffix is not provided. The default created /etc/nginx/nginx.conf file contains time values that do not have "s" suffix.
Please refer to the following discussion for more context:
https://github.com/voxpupuli/puppet-nginx/issues/1137
Following is extracted from the URL above:
Looking at the nginx source code it seems to me the values are interpreted by default in miliseconds, eg. the source shows:
ngx_conf_merge_msec_value(conf->keepalive_timeout,
prev->keepalive_timeout, 75000);
ngx_conf_merge_msec_value(conf->client_body_timeout,
prev->client_body_timeout, 60000);
ngx_conf_merge_msec_value(conf->send_timeout, prev->send_timeout, 60000);
ngx_conf_merge_msec_value(conf->lingering_timeout,
prev->lingering_timeout, 5000);
The documentation is correct, time values without the suffix are always interpreted in seconds. Please see the code in
ngx_conf_set_msec_slot(),ngx_conf_set_sec_slot(), and the logic behind the last argumentis_secinngx_parse_time().Explanation:
ngx_parse_time()returns the value either in seconds or milliseconds, depending on the last argument's value. In both cases, the input passed without any suffix is interpreted as a value in second (and gets multiplied by 1000 in case the function is instructed to return milliseconds). That's why you see the default values in milliseconds inngx_conf_merge_msec_value()calls.
