I need to find if a person is located within the given zone by user's current GPS location (latitude and longitude).
For instance, I have a user GPS location and how do I find out which zone he is at?
Any API service able to do that? How to map the zone area?

I am building an app where users can find events within a given location.
For example, if the given location is Europe, it should return all events with locations within Europe.
I have no idea how to go at it, if there is an API that I can use or anything.
Any suggestions?
I'm an amateur photographer. I have Video, Mobile, Camera, Drone, etc. My goal is to sync all data on the right time and add GPS tag.
I end on configure everything on UTC (except mobile), and add after GPS tag that is on UTC also.
Main problem is how to determine correct timezone based on where the picture has been taken, and if I have to, since all my mobile photos has the timezone (and daylight savings) applied when taking video/photo.
I'm using now an OPEN API for having the correct GMT based on the geolocation and time/date.
Am I doing it right? Am I interpretating DATE/TIME changes correctly? I saw after that Lightroom changes based on the date/time info and the place it's used (photos).
It's a mess.
i am using SIM7600G GSM module to get the location information without using GPS in it. Anyone know about how to find the location from GPRS SIM itself?!
If such information could have been obtained from a device it wouldn't be the SIM but the GSM hardware. What you can hope to get is the cell ID of the serving cell, typically using AT commands, but this is not always true for all devices.
Depending on your country, you can find the position (longitude, latitude) of the site bearing that cell (there exist some databases). Depending on site location, urban zone or rural zone, you can approximate the position of the device within the coverage area of the cell from some hundreds meters (urban) to few tens of kilometers (rural zone where the network is usually much less dense), the theoretical maximum being 35Km...
The only way to have a precise position is by using the GPS
I've been looking for a while now and have done a good amount of research as well as experimenting, but I cannot find a way to retrieve the value stored in a users settings for Time Zone Support on iOS devices.
I have looked into NSTimeZone convenience methods +systemTimeZone, +resetSystemTimeZone, +defaultTimeZone, +localTimeZone. I even fully understand the differences between them and how we can set our own default time zone per application, and how first call to default returns value for system. System then gets cached and needs to be reset if the device changes time zones.
Problem is, systemTimeZone is always where the device is actually located, not the value set in the device's settings under Time Zone Support.
I have even looking into [[NSCalendar currentCalendar] timeZone] as well as [[NSCalendar autoupdatingCurrentCalendar] timeZone]].
I even tried [[[NSLocale currentLocale] objectForKey:NSCurrentCalendar] timeZone] and [[[NSLocale autoupdatingCurrentLocale] objectForKey:NSCurrentCalendar] timeZone]
Nothing returns the value of the device's Settings.app -> Mail, Contacts, Calendars -> Time Zone Support -> Time Zone.
Does anyone know how to retrieve the value of the Settings.app -> Mail, Contacts, Calendars -> Time Zone Support -> Time Zone setting?
Thanks and Cheers!
Forgive me if this is way off the mark, but are you sure that you actually want to access the Time Zone Support setting from the following location?
Settings.app -> Mail, Contacts, Calendars -> Time Zone Support
I would not have made this post otherwise, but you got me thinking when you stated the following:
Problem is, systemTimeZone is always where the device is actually located, not the value set in the device's settings under Time Zone Support.
Unfortunately, your statement here is not quite correct. +systemTimeZone will return the time zone for where the device is actually located unless the user has turned off Set Automatically and chosen a particular time zone at the following location:
Settings.app -> General -> Date & Time
This will change the time zone to be used system-wide, which is immediately reflected by the time in the status bar adjusting for the new setting.
What you have been trying access previously seems focused on how calendar appointments are represented in the native Calendar.app, and would appear to be private to that application (along with the rest of the settings in that area).
If you are looking for access to the effective system-wide time zone setting that can be modified by the user then Time Zone under Date & Time is the way to go. This will be the value returned by +systemTimeZone.
On the other hand if you really must access the Time Zone Support setting under Mail, Contacts, Calendars I'm afraid I cannot help you and I apologise for the distraction.
I have an online website portfolio and I want to put their the current time in our country and also I want to put the weather update there. If my clients browse it they will see the time in our country.
My question is:
What script should I used?
Example: I live in Philippines so thats GMT+08:00
Then, when someone browse my website from any country they will see the Philippine current time not their computer's time.
Load the time on client side that is through java script instead of server side. Then time will be displayed based on client side time zone.
