Fetch current time in 24 hours format in JMeter

Question

How can I get current time in 24 hours format in JMeter.

I tried ${__time(hh:mm a,)} but it results in AM/PM format.

Answer 1

In Apache JMeter 5.2, current time can be captured in User defined variable and then used in Rest payloads as following screenshot:

expression - ${__timeShift(yyyy-MM-dd'T'HH:mm:ss'.000+05:30',,PT0S,,)}

output - "2020-06-06T18:10:59.000+05:30"

Here, date and time format can be changed as per the need.

Once current date and time is captured in user defined variable then it can be used as "${now-date-time}" in REST requests.

It could also be possible that we face a scenario where there should be gap of, let's say, 1second between start time and end time while constructing request. In such case, following expressions can help:

now-date-time : ${__timeShift(yyyy-MM-dd'T'HH:mm:ss'.000+05:30',,PT0S,,)}

now-date-time-plus-one-second : ${__timeShift(yyyy-MM-dd'T'HH:mm:ss'.000+05:30',,PT1S,,)}

Following example better explains it:

Answer 2

As per How to Use JMeter Functions guide JMeter's __time() function output can be controlled via SimpleDateFormat class patterns.

Looking into JavaDoc:

• you don't need a letter
• you need to use capital H for 0-24 hours or lowercase k for 1-23 hours

So change function to ${__time(HH:mm,)} and that should be it
