ngx.say('ngx.time()' .. ngx.time())
ngx.say('ngx.now()' .. ngx.now())
ngx.say('ngx.today()' .. ngx.today())
ngx.say('ngx.localtime()' .. ngx.localtime())
ngx.say('ngx.utctime()' .. ngx.utctime())
ngx.say('ngx.cookie_time(1500456075)' .. ngx.cookie_time(1500456075))
ngx.say('ngx.http_time(1500456075)' .. ngx.http_time(1500456075))
ngx.say('os.time()' .. os.time())
ngx.say('------')
ngx.say(ngx.update_time())

结果：
