OT: New time zones?

[Mark Lloyd]

Not quite. The sig separator is "-- ", there is a space at the end.

This year only? If not the general rule (like second Sunday in September) would be more useful.

Good. I know Russia has already done so. I hope more countries will do this.

[Rod Speed]

Dont have that problem anymore given that all the computers and the mobiles always have perfect time.

But not practical for the reason someone else spelt out.

[Commander Kinsey]

And my phone has to be restarted just to take account of this? ROTFPMSL!

[Chris in Makati]

It's this year only due the country holding a referendum on a new constitution on September 4.

Next year it will back to normal; the first Sunday in September.

Greenwich Mean Time (GMT) isn't necessarily the local time in Greenwich. It's the time at which the sun reaches it's highest elevation over the Prime Meridian line in Greenwich Park.

That is exactly why GMT does not exist anymore. It is called UTC and is completely independent of any interference of local authorities.

Technical installations including satellites are using UTC around the globe. Some also call it Zulu-Time. Particularly military, aviation and maritime organizations. Zulu is equivalent to UTC+0.

Replacement of data is only possible when the file concerned is not in use. That applies to all OSs.

[Commander Kinsey]

That shows a complete lack of decent programming. I remember the old Macs, you had to restart to install a printer driver! Stop using the flie, replace it, start using the file, why restart everything for one function?

[Scott Lurndal]

No, it does not apply to unix and unix-like systems. Including android. The TZ database can be updated at any time. Applications may, or may not reflect the updated database until restarted depending on the quality of the application and whether it caches tz data.

[Carlos E.R.]

Unfortunately, Android is not using a Linux filesystem, but FAT.

In Linux, a file used by an application can be updated on disk; the application holds the file open by a handle which points to the old data on disk, which will actually be gone when that application closes or restarts. That is, for some time both versions of the file are on disk. This mechanism is what permits live updates.

I fear that FAT doesn't support this type of operation.

[Commander Kinsey]

Why would it have to? Surely the OS can signal to those apps the file is being changed, so they reopen it when you've downloaded it.

[Carlos E.R.]

This is done when the update package lists those services that have to be restarted when applying the update. Not as a generic "OS signals apps that opened the file that the file has changed".

[Commander Kinsey]

So you restart some services, big deal, no need for a reboot.

[Carlos E.R.]

Which can not be done on Android, you do not have access to the services.

[Commander Kinsey]

The OS does, which is what would be carrying out the timezone upgrade.

[Carlos E.R.]

Which requires a complex logic. As this could not be done easily, they tell you to reboot. Cheaper.

Move on :-)

[Commander Kinsey]

By "cheaper", you mean "using inadequately skilled programmers." it's amazing how many mistakes there are in modern programs. And why does my mouse driver require 130MB when a mouse driver in 1991 was 40KB?

[Carlos E.R.]

Nope. Less programming time.

1 It does much more 2 Less programming time.

[Commander Kinsey]

it does not. it monitors two buttons and a wheel and the direction I move it in.

So we all have to make do with much more powerful computers which can't actually do anything better or faster, because of lazy stupid programmers.
