I would like to monitor AWS using HTTP agent items.

A get request to AWS requires the "StartTime" :, "EndTime": parameters.

https://docs.aws.amazon.com/ja_jp/AmazonCloudWatch/latest/APIReference/API_GetMetricData.html

Macros can be used for the Request body parameter of the HTTP agent.
However, there is currently no macro in Zabbix that returns Unixtime.

In order to make a request to AWS periodically with HTTP agent, it is necessary to specify the data period to be acquired by Unixtime, not fixed Request body.

Future or past of specified number of seconds
And I need a macro that returns Unixtime for the current time.
