1308	nginx timer don't work if change system date.	panjiearray@…		"I register a timer used by function ngx_add_timer(), and it works well. When time expire, event handler will execute. 
But if I change system date, for example, today is 2017/7/4, I change system date to 2017/7/3, then nginx timer can not work well, and no longer trigger event handler.

Is it a bug? or I don't understood how to use ngx_add_timer?

Please help, thankyou."	defect	closed	critical		nginx-core	1.12.x	duplicate	timer		Linux AN 3.10.0-327.28.2.5.el7.x86_64 #1 SMP Tue May 9 23:37:12 EDT 2017 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.12.0
