How to synchronize clocks for a different item

[ecamy]

Hi,group,
I am trying to synchronize clocks for all items in order to better analysis data , but I can't find the entrance to implement this function in zabbix. Can you help me?
Please see the chart as below.
Thanks!

My Version: zabbix3.2/Centos6.6

You can set update interval based on the clock using Custom intervals in agent checks.

Thanks Dmitryb,But all my interval is right(5s), The starting time of item clock is not same. Someone tell me that depend on the creating time of an item, but I believe zabbix should have a better solution.

Please read Dmitryb's answer carefully.
He wrote that he tried using "Custom intervals".

Please check the manual for details of the "Custom intervals".

https://www.zabbix.com/documentation/3.2/manual/config/items/item/custom_intervals

By using this you will be able to get the value closer.

Thanks so much Atsushi. I can custom any sequence of time for monitoring according to your hint now. The key step is Custom intervals -> Scheduling intervals -> input format string, which is so simple and convenient. Please forgive me for not better understanding Dmitryb's response last night. I will try many times later.

No matter my careless, I should appreciate your strong tool, zabbix, which can help me collect hardware metrics for my research. Thank you for your timely help again.
