|1653 - Minor annoyance with clocks|
"A man with one clock knows what time it is. A man with two is never sure."
There are five clocks within my direct line of sight as I type at my office Mac: the Mac itself, of course; a car radio I have set up so I can listen to local severe weather alerts and such; the indoor/outdoor thermometer (it's 84.1 F out there, a nice comfortable temperature); and two VCRs. One of the latter is the latest source of annoyance.
They're both Sony decks. One is a fairly old SL-2700 Beta; the other, a fairly recent SLV-N51 VHS. Both are hooked up through some switching and a video processor to a Canopus ADVC-100 grabber for video work.
The clock on the Beta deck drifts a second or so a month, and gets reset against the Mac whenever I notice. The clock in the thermometer is largely ignored, since it's not very accurate at all. When it's drifted 5 minutes or so, it gets reset. The clock on the Mac is dead on, since it's synchronized with a time server Apple runs via NTP.
The clock on the VHS deck is supposed to be set automatically. I gather that it sucks a time signal off one of the TV stations on the cable and sets itself daily, at 9 PM. There's only one problem: It's two hours off, and has been ever since the power outage we had a week or so ago. Occasionally it resets to something even more entertaining, but it hasn't been right since the outage. There's a Toshiba VCR in the bedroom that also sets itself automatically, and it's right. I checked the settings on this one, and everything's set to auto: channel to set from, time zone, and setting enable.
I don't know why it's off, but it's beginning to irritate me.
current mood: annoyed
current music: Led Zeppelin - Street Corner Girl
Have you tried drop-testing it yet? ;)
I'm not quite that annoyed with it.
Yeah...that is irritating. For NTSC TV signals, Line 21 contains time of day, program, network, ratings, and other info as well as closed captioning, so these days anything that has a TV tuner in it has no reason not to have the correct time.
I got it straightened out: I forced it to set the clock from one of the two PBS stations on the cable. (The other didn't work, for some weird reason.)
