IT Advisor API Question : install date

[MichaelTelford]

I'm using the IT Advisor REST API and I'm trying to parse the installDate field available on most assets.

It looks like the field is the number of milliseconds from some Epoch date, but I wasn't able to find the exact date in any of the documentation.

Here's a few example values from my site:

installDate: 1578632272450

installDate: 1578632305054

installDate: 1578632331520

Using Jan 1st, 1970 gives plausible results, but I need to know the exact time & date to use, and if the install date is UTC time or local time to give a correct conversion.

As far as I can tell, this date isn't available in the Web or Software UI, only the audit log which, again, gives me a plausible but not exact value for installDate.

Thank you!

Hi @MichaelTelford, 

ITA uses Unix Epoch time, which is the number of seconds or milliseconds since 1/1/1970, which we use milliseconds.  This time should be in Greenwich Mean Time (GMT) as per my testing.

installDate: 1714613227696

Converted installDate using a epoch time converter:

Converted installDate time using an Epoch time conversion online tool.

GMT around the time the asset was created:

GMT time at the time the asset was created.

This shows that 1/1/1970 is used as the date, and that GMT time is used for the stored value.  Hopefully this helps!

Regards,

Cory
