but when the man-made TIME CHANGES from daylight savings time to daylight standard time on THAT DAY you have 25 hr's lets count them 0000, 0100, 0200, (man made time change becomes 0100), 0200(again..!), 0300, 0400, 0500, 0600, 0700, 0800, 0900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2200, 2300, 2400
sure looks like 25 hr's
or try this at midnight tonight set your screaming meanie for 24 hr's and see what time it goes off..... hint hint 2300Last edited: Nov 5, 2011

That still does not null the 24 hours in a single day for truckers logging HOS. The Time Change is only an adjustment on the log. I have been searching for a solution and find the DOT can only accept that you log your duty status with a flag where the DST fell.
For example: you start at 00:00 at the hours between 02:00 and 03:00 you note two lines on line three, this accounts for 2 hours being credited toward your 11,14 hour clock. same as if you where in the sleeper.
The DOT man is smart enough to recognize any attempt to work 12 and record it as 11 on duty driving. As far as E-Logs the calculations, programmers have already addressed the variances of DST and the unit will still recognize 11 hours on duty driving no matter what time zone or DST adjustments take place during a twenty-four hour period.
I have E-logs on board and the adjustment is automatic, I do not have to make manual adjustments as would someone using paper-logs. But anyhow you slice it or dice it the laws of nature (celestial mechanics)forbid changing 24 in 23 or 25. It is what it is!Last edited: Nov 6, 2011

It's going to count 11 hours. If you start at midnight and drive till 11am, you're going to have a HOS violation. -
BTW, the earths orbit around the sun doesn't dictate the length of a day. It's rotation does. The speed of the earths rotation does not change because the earth rotates on it's own axis. The earths tilt dictates DST, just as the earths tilt dictates our seasons.
Oh, and I've been eyeballing my EOBR tonight. I've been at the yard in SLC all weekend. At 1:59am MDT, I had 45 hours and 5 minutes logged on line 2. According to you, my EOBR should have lost a hour during the change, sending me back to 44 hours and 6 minutes at 2:00am. Guess what? Didn't happen. I didn't lose a hour and I'm showing 45 hours and 7 minutes on line 2. Instead of showing 45 hours and 6 minutes at 2:00am MDT, it's showing 45 hours and 6 minutes at 1:00am MST, and that hour is FLAGGEDLast edited: Nov 6, 2011

DST does NOT add or remove time from a 24 hour calendar day. Last time I checked, mankind doesn't have the technology to change the speed of the earth's rotation at will. -
