Hi,

The time stamps on my incoming mail are off by one hour. Did Gmail
change to Double Daylight Savings time over the weekend?

I thought the problem had been solved. I got a notification from
Google Calendar an hour early. The second notification was at the
right time.

How do we get Google to notice and fix this?

Ciao,
Linda

It might be that something is amiss on your computer.

The rest of my emails through this group (except for the one sent at 2:30am)
are coming through with apparently correct times: "Sent" time is slightly
before "Received" time. Your email, on the other hand, appears to be one
hour off. That could imply that the "Sent" time, which was marked by your
computer when you sent it, was an hour off.

Why would the time on my computer be involved? But, in any case, I
reset the time on my computer early this morning, hours before posting
here. Yes, it had gone to double daylight savings too. The other
reason I don't think it is my computer is that the times are correct
now. I think someone at Google noticed and fixed it.

"If the time displayed on your messages does not match your system
clock, there may be an issue with the time zone listed in your Google
Account settings."

It tells me to check the settings on my Gmail account. I checked, the
time zone is correct. It then tells me to check the settings on my
system clock. They are correct.

Why the heck would Gmail look at my system clock to set the time on
the messages? They use their own clock. They store my mail on their
servers. And, since the problem went away without me changing any of
my settings, I can assume that Google discovered that their system
clocks had gone to double daylight savings.

All I really wanted was a way to inform Google that they had a
problem. Next time I will just contact a friend who works for Google.

We certainly had some problems in Australia as Daylight savings was
extended by a week compared to normal and not all equipment was smart
enough to recognize this. My computer was OK but my PDA ended up out
by an hour (or maybe its just us Ozzies)

Just for reference, it's not only the current time on your computer that
matters; it's also which time zone your computer thinks it is in. This is
more important than you may think.

With the recent changes in Standard Time /DST, many computers didn't have
the time zone correct.

One result of this is that your computer may incorrectly interpret the
timestamp on received email. It needs to translate the times in the header
of the email, into your local time zone. If your computer has the wrong
time zone offset, even though the computer's clock shows the correct wall
clock time in your area, that translation would be wrong. (I know this from
experience ... it happened to me, after our country's new change to DST back
in March. I had manually reset the computer clock, but things still were
not right! I downloaded a patch, which fixed everything.)

Your outgoing email gets affected too, because your computer attaches the
time (along with what your computer thinks is the offset from UTC/GMT) to
the outgoing email.

Um, those two statements are in conflict with one another! If your computer
"had gone to double daylight savings too," then your computer did not have
things right, and you DID change your computer's settings!

Did you read the part where I wrote that I checked the setting for
time zone and it is correct?

I guess I need to clarify. Yes, my computer went to double daylight
savings. I noticed this because I got a Google Calendar notification
an hour early. So I checked the time on my phone and on my computer,
and finally against the news on TV. The computer was an hour early. I
changed the time by one hour.

I noticed the problem with email after I changed the time, but not the
time zone. At some time I posted here and got a reply with a link to
check my settings. I checked Gmail settings and computer settings and
they were correct. At some time after that, the problem went away. Is
that clear now?

I suspect this was caused by the US deciding to extend daylight
savings time. I live in Canada and work in the US, so for a while there,
until Canada caved, it was looking like my commute was gong to take an
hour longer one way and an hour less the other...

Don't you think it's a bit astounding that your computer clock was off
at the exact same time that Google's clocks were off? And that Google
fixed the time at the same time you fixed yours?

Just throwing that out there.

It would have astounded me if it were the same time and not just the
same day. And the problem was first noticed with Gmail AFTER I fixed
the time on my computer. A number of hours later, the problem went
away.

I guess some people here just don't read.

That is exactly what I think the problem was. BTW, I'm in Canada too.

For what it's worth ---

Having the correct time zone is not just a matter of looking up that it says
Pacific (or whatever). What I am referring to are also the settings that
affect Standard vs. Daylight Saving time, AND the date that it changes.

For computers running Windows, this is apparently stored in the Registry,
in the form of a string of numbers. Some of it is not even human-readable.
Having (a) the correct zone (Pacific, Eastern, whatever) and (b) the correct
time, is NOT SUFFICIENT to have your computer date things right.

Me, I thought I was all set when I changed my computer's clock ahead one
hour on 9 March. But I started getting emails with timestamps that didn't
make sense. Of course I figured it was the other guys' computers, until I
noticed it was happening to my own emails too. I even tried faking the time
zone in my computer, to no avail. Then I did the Registry patch for the
changed Daylight Saving time in the USA, which re-programmed that string of
numbers, and everything was fixed.

If your computer set itself to double-Daylight Saving time on Sunday four
days ago, then it isn't fixed yet, and this problem will keep happening
every autumn and spring. Manually resetting the computer's clock won't fix
it either, even though it might look like it does.

The computer I'm on now is an older one, and I got the patch for it at
http://solprovider.com/articles/win98timezones .

Andy,

You are probably right that my operating system needs a patch. But,
that still doesn't explain why the problem solved itself several hours
after it first showed up and I didn't fiddle with any settings between
the time it first showed up and the time it corrected itself.

I'm just not going to worry about for now. The problem is gone.

Linda
