I'm working on a simple project. The basic idea is that the user can only do something once a day. If I grab the SYSTEMTIME from the device, there is a chance the user will change the time on their phone to exploit the program.
So I don't want to use local/device time.
I looked into Googles API, but it looks like it returns the timezone and requests a timestamp. So that's not what I need.
But I found this website: http://www.convert-unix-time.com/api
This is perfect! But I don't know much about timezones/conversions/unix time/special clock things.
Is this grabbing the time from a server (that the user couldn't possibly alter)? Or is this grabbing the time from my computer and converting it to JSON output? Any additional information would be greatly appreciated.

I'm sending data to Splunk and everything is working just fine, i can see the data that i'm sending and run a query and get results. Right now I'm only using a test data set, but eventually people will be sending their own fields (as well as the mandatory ones). My question is, since I don't know what kind of data they will be sending, can I still set up alerts for them? Can I create something general?
It's pretty hard to create a generic alert that's actually useful. You may be able to craft something using the mandatory fields, but it may not be all that helpful.
If you're opposed to letting users create their own alerts then let them come to you with what they want.
I want to automate some tests where I have to manipulate the system time to check for authentication behaviours of a program that is written in golang. According to this post, libfaketime does not work with golang. Is there another way that I can achieve what I want to do with libfaketime?
Here's a description of what libfaketime does from github.
libfaketime intercepts various system calls that programs use to retrieve the
current date and time. It then reports modified (faked) dates and times (as
specified by you, the user) to these programs. This means you can modify the
system time a program sees without having to change the time system-wide.
No, there is none.
You need to use something like clockwork (see this for more) and explicitly pass "time" implementation around your code.
Update from 2021-03-01 with a more up-to-date list of options:
https://github.com/LopatkinEvgeniy/clock
https://github.com/jonboulle/clockwork
https://github.com/benbjohnson/clock
https://github.com/facebookgo/clock
https://github.com/tkuchiki/faketime
https://github.com/rzajac/clock
There is this repository (tkuchiki/faketime) which claims to be able to fake the time.Now()-function. I don't know how extensively this works and haven't tested it. But it sounds like it might be a solution to your problem.
What I am doing is, I have recorded a download event from APP on Jmeter, when ever i am running this API on Jmeter, a server where any download event is recorded, is showing OR increment that download on that specific time when it was recorded.
How can I use this to get updated data on server when Jmeter is running.
Also need some information on to how to add different valid users on Jmeter.
Thanks,
Abhi
My expectation is that you pass a hard-coded timestamp as a request parameter so you need to figure out the parameter value and substitute the hard-coded timestamp with __time() function which produces current time in different formats controllable via SimpleDateFormat patterns.
Check out How to Use JMeter Functions article for comprehensive explanation
In regards to adding valid users, normally people stick to users which already exist in the system and use CSV Data Set Config to give each JMeter virtual user unique credentials of the real user.
If your application doesn't have that much users you might want to setup a separate JMeter script to get them created as re-using one login with large number of threads is not a good practice.
I made a program that gets the data from the clipboard and saves it in a string variable. Then it looks for specific words in that string and generates several URLs. Afterwards it open the browser and shows each URL in an own tab.
Some of my friends already use this program frequently and I want to have some statistics about how often. I simple counter variable would be enough but I need to get access to it.
I came up with two options that could work:
I could send an email to a specific adress every time my app is executed. Then I can track the amount of uses by manually or automaticly counting the amount of emails in the postbox. I think this would be a Vers dirty solution.
I could create and publish a website containing a counter. This counter could be refreshed by my application. This solution is a bit better I think but a lot more work for just one single counter.
Do you have better ideas to solve my problem or is one of mine already a good one?
Thank you in advace!
You can use Measurement Protocol Overview. This provides you statistics of usage your application compared with Google Analytics. You can see even a geo statistic, version distribution, crash reports. It is easy to use it from .net. It is just about requesting http request to google.
I've implemented the code from http://satalketo.com/2013/09/mvc-two-factor-authentication/
Two Factor Authentication in ASP.NET MVC
when user register he gets a Secret Key and shown a QRcode he can scan to Google Authenticator,
all works fine and well, accept when the user tries to Log In the system the key always different from the one he enters. function GeneratePin at server side generate different key from that he gets in the Google Authenticator mobile app. I have no idea whats wrong, tried to think maybe time zone isn't correct ,my time zone is Jerusalem UTC + 2
I've looked through my code a fair bit and I can't see any reason why this should be an issue. The only reason that I can come up with is that one of the two devices is more than 30 seconds out of sync with UTC.
I have updated the source code to include checking against the 30 second periods either side of the current one to try and deal with any situations like that.
You can find the updated code on GitHub, which would be the best place to download the entire solution. My article Two Factor Authentication in ASP.NET MVC has been updated to include the code for checking the period either side.
If this doesn't help please let me know with any additional information you can think of.
