I have a API Test Plan that runs on JMeter with timestamp Parameter inside body that requires current timestamp in UTC YYYY-MM-DDTHH:mm:ss.SSS format.
e.g. timestamp: "2021-07-15T12:00:51.308Z"
Can someone help me with this on what & where function to be written and call so I don't have to manually change timestamp every time before I run my Test Plan
If you want to get the current timestamp in your local time zone - go for __time() function:
${__time(yyyy-MM-dd'T'hh:mm:ss.SSS'Z',)}
If you're in the different time zone and would like to get the current timestamp in UTC - go for __groovy() function:
${__groovy(new Date().format("yyyy-MM-dd'T'hh:mm:ss.SSS'Z'"\, TimeZone.getTimeZone('UTC')),)}

Use __timeShift with required format:
${__timeShift(yyyy-MM-dd'T'hh:mm:ss.SSS'Z')}
Output: 2021-07-15T03:44:27.791Z

We have below code for "Date" in LONG format in one of the requests in Jmeter
SubmittedDate":{"value":1672986618263}
_CreatedDate":{"value":1672986618264}
Please help me to how to handle to get current date and time in Long format during replay or run time
Thanks
It looks like to be the timestamp in milliseconds since the beginning of Unix epoch, in JMeter there is __time() function which returns current timestamp.
If you want the "CreatedDate" to be 1 millisecond larger than the SubmittedDate you can use __longSum() function
Something like:
SubmittedDate":{"value":${__time(,created)}}
_CreatedDate":{"value":${__longSum(${created},1,)}}

I want to fetch record from the sys_user table which is updated at or after certain time stamp.
for that I have created rest request as
https:/service-now.com/api/now/v1//table/sys_user?sysparm_query=sys_updated_on>=javascript:gs.dateGenerate('2017-10-30','01:25:00')
I had converted current time which is in IST format into GMT and pass it to dateGenerate() function.
Problem statement -
I don't want to convert the IST to GMT, is there any way by which i can identify ServiceNow instance time zone at runtime and convert given time into that time stamp and get the users.
If i can pass this date and time in UTC format.
Ahoy!
This is a great question, and something that's quite difficult in ServiceNow (dealing with time-zones).
As such, I've written a tool to manage this for you. It's totally free!
The tool is called TimeZoneUtil, and can be found here:
https://snprotips.com/blog/2017/9/12/handling-timezones-in-servicenow-timezoneutil
You simply need to initialize a GlideDateTime object, set its' time-zone to IST, use setDisplayValue() to set its' time based on IST current time, then use .getValue() to get that same time in system time.
This is because getDisplayValue()/setDisplayValue() work based on time-zone, whereas setValue()/getValue() always return the corresponding system time.
EDIT: In order to make this a little more clear, I'll provide some example usage below.
var tz = new TimeZoneUtils(); //initialize with current time
gs.print(tz.getOffsetHours()); //prints out "-7" in my instance, as the system time is in Pacific.
tz.setTimeZone('Asia/Kolkata'); //sets the time-zone to IST/UTC+5.5
gs.print(tz.getOffsetHours()); //prints "5.5".
gs.print(tz.getGDT().getDisplayValue()); //Prints the current time in IST (2017-11-01 20:52:31 at the moment).
gs.print(tz.getGDT().getValue()); //Prints the current time in system time (2017-11-01 15:23:12 at present).
gs.print(new TimeZoneUtils().setTimeZone('Asia/Kolkata').getDisplayValue()); //Single line, also prints current time in IST: 2017-11-01 20:52:31
The first 6 lines there, demonstrate basic usage and explain how it works.
The eighth line however, demonstrates usage on a single line, which you can use inside a query string. For example:
sysparm_query=sys_updated_on>=javascript:new TimeZoneUtils().setTimeZone('Asia/Kolkata').getDisplayValue()
Hope this helps!

I am new to Jmeter and working on JDBC. I am interested to know:
How to change field/header names while exporting data to csv file.
How to display elapsed time in seconds instead of milliseconds.
I would really appreciate, if you please define each step. Being a newbie, it would be easier for me to follow.
The field names are defined in the CSVSaveService.java file, you will need to get JMeter sources, amend field names as required and rebuild JMeter. See How to write a plugin for JMeter article for more information
There you can change it in the same file like:
elapsed = Long.parseLong(text) / 1000 // convert ms to seconds
However I wouldn't recommend going for these approaches as there could be side effects in reporting systems.
Instead of patching JMeter you can add a JSR223 Listener and write your own CSV file using Groovy code
For example this is how you can write elapsed time in seconds into a new file called results.csv
def myFile = new File('results.csv')
myFile.append(sampleResult.getTime() / 1000)
myFile.append(System.getProperty('line.separator'))
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.
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
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:
Anybody please let me know, how to get the response time of each transaction in seconds/minutes/hrs not by milliseconds ?
How to configure the test plan for each transactions separately in jmeter?
for example, transaction : load task, transaction : save task,
transaction : login and transaction : sign out.
in seconds/minutes/hrs ?
It isn't possible on "per transaction" basis but it's something that you configure globally.
Looking into jmeter.properties file in /bin folder of JMeter installation:
# Timestamp format - this only affects CSV output files
# legitimate values: none, ms, or a format suitable for SimpleDateFormat
#jmeter.save.saveservice.timestamp_format=ms
#jmeter.save.saveservice.timestamp_format=yyyy/MM/dd HH:mm:ss.SSS
See SimpleDateFormat JavaDoc for possible values.
You can specify format required by uncommenting and altering jmeter.save.saveservice.timestamp_format property as follows:
jmeter.save.saveservice.timestamp_format=HH:mm:ss
Or specify it as JMeter startup script parameter as:
jmeter -Jjmeter.save.saveservice.timestamp_format=HH:mm:ss -n -t /path/to/your/script.jmx -l /path/to/logfile.jtl
See Apache JMeter Properties Customization Guide for more details on how to make use of different JMeter properties.
