This is probably too trivial and a waste of bandwidth, for an article. But could someone explain why my fitbit says it is 1.07pm. my laptop is 1.10pm, my phone is 1.08pm and the TV Weather Channel shows 1.08pm.
Seems like they should all be in sync!
For my part, I admit to some hesitancy to engage a thread dealing with “strange stuff” about “my equipment.”
Perhaps Laz can explain...
I’m trying to figure out why my computer makes a tone
when I open my refrigerator door.
Does anybody really know what time it is?
Maybe ask Leonid & Friends.
My laptop identifies as a toaster.
LOL...never saw that before. Thanks for the link. It’s hilarious — but I’m sure we all see ourselves a time or two.
Can’t put his groceries in his refrigerator because it’s full.
Can’t get wifi in his kitchen because his house is so big.
LOL.
You want to hear strange?
Someone turns on a particular fluorescent light in another room.
When they go to turn it off, my right monitor goes black.
5 seconds later it comes back on.
Somehow it reminded me of that old joke That explains why cannibals don’t eat clowns because they taste funny… :-)
Love it...!
Overclocking shouldn’t actually affect the system clock. That’s an entirely separate chip from the motherboard.
OK. Thanks.
Maybe I’m thinking commodore 64 tech?
LOL
Each of the devices is probably keeping time with its own “software clock” (the pc also has a hardware clock that is more accurate and it updates the software clock from time to time). Mobile devices probably check some server to get the time occasionally and update their software clock to the correct time. But in between updates, you’ll see these little variances build up.
Maybe, I don’t know if C64 had CMOS chips, I never owned one of those.
Even if all of your devices get their time from the same source they can be out of synch due to network and server latency.
Four different devices may have four completely different ways to communicate time to your devices.
One goes through Denver, Beijing, Tokyo, an NSA data monitoring center in Utah, and then to your device.
Another goes through Chicago, two NSA data monitoring centers, and then to your device.
Yet another goes through Frankfurt, Mumbai, the NSA, and then to your device.
The last one goes through Mexico City, Singapore, the NSA, Chinese intelligence, Facebook, and then to your device.
Each path has a different route for the data and if you know about ping rates and traceroute you can prove this to yourself.
Fitbit updates time and data on sync with your phone. If they have drifted significantly, you need to sync more often. Mine syncs multiple times throughout the day, so both display the same time.
Internet of Things connectivity. Likely an BLE (Bluetooth Low Energy) beacon off the refrigerator being picked up by the Bluetooth on your computer.
Does anybody really know what time it is? Does anybody really care?
You can configure your laptop to synchronize time to the network NTP servers. Unless you lack a network connection there is no reason to not configure network time sync. Your cellphone will sync time to the cell tower...GPS accurate time.
Are you logged in to all of these devices?
A man with two clocks is not so sure.
