How to get the Last Visit Date of a user in remote api?

I have taken the last visit date it is a long value 1481116010. is there any ways to format it to a normal date ?

How to get the time zone value of a user

Hi My user's timezone in user settings is (+5:30) value is 19800. But when i took the tz value in remote api "core/use_auth_hash" i get the tz value as 134237528. Why is that? Am i missing something?

Hi I have refer to that link.  and when i tried to do the timezone conversion to my dates i am doing like the below. But the calculation is getting varied for different timezones. can you please specify a common logic or javascript method where i can pass my input and timezone value and get my converted output.

//For -28800    Pacific Time (US & Canada)    -08:00, I need to do the below calculation to get the result
var tz = (-134180992 & 0xffff) | 0xffff0000;
var ld = 1479391853;
console.log(new Date(((ld - (-new Date().getTimezoneOffset() * 60)) + tz)* 1000));


//For 19800    Chennai, Kolkata, Mumbai, New Delhi    +05:30, I need to do the below calculation to get the result
var tz = (134237528 & 0xffff) ;
var ld = 1481631941;
console.log(new Date(((ld - (-new Date().getTimezoneOffset() * 60)) + tz)* 1000));

thanks deal

ramesh, timezone and dst is combined in one property tz. See details and example here https://sdk.wialon.com/wiki/en/sidebar/ … time/start

ramesh, this is correct. This function returns only timezone offset value in seconds. But DST offset can only be applyed to certain time. Because winter time differs with summer time.
There is special function in SDK JS to get dst for certain time (getDSTOffset) and to format time according to timezone and dst (formatTime). But Remote API operates with raw unix time. And You should format this time yourself. You can calculate dst value by yourself or using some third party library having user's timezone offset value and dst flag.

ramesh, calculation of DST offset is implemented only in Wialon SDK JS. And this calculation is not very simple.
There is no such function in Remote API. You should do it by yourself. We can't provide You with realization of DST calculation function on your programming language.
DST offset is not calculated in Your function (only timezone offset) and thus it is not applied to time. The only solution for now is to use third party library which can give you dst offset value according to user's timezone and dst flag.
We will try to find solution of this problem. But such feature can't be made soon.

Hello,

I am one of developer in Fleetilla(https://fleetilla.com/) product.   Currently I need to send Timezone with day-light-saving details from our admin system to client-system of FleetFACTZ. 

Example Timezone,
1. ET(Eastern Time (US/Canada) with DST and without DST
2. AKT(Alaska Time (US/Canada)) with DST and without DST
3. IST(India Time) without DST

Please find all timezone in the attachment, which are used timezone and the attachment contains the sample screen-shots.

We are stored above table timezone-info to our admin system.  Find the below screen-shot for FleetFACTZ system - the User-Setting dialog-window.  We expected which data/info wants to send to FleetFACTZ system for storing and retrieving the timezone with day-light-saving data/info for populate the timezone and day-light values to the “User Setting” dialog-window screen in FleetFACTZ systems. 

Kindly guide me to use to send the timezone with day-light-saving info to FleetFACTZ systems and which custom-property we need to use and sample details.
