I suspect the hardware engineer would explain the great favour he’s doing you by handling all the handling of all the weird splits between things like hours, minutes and days for you in hardware logic, rather than you having to waste previous cycles of your MCU’s core to do that sort of thing. But it is indeed a real pain when you want dates in more abstract than human forms…
- JohnFen 3y agoYeah, that hardware engineer isn't really doing anyone any favors.
- JdeBP 3y agoThe rest of us, including a number of hardware engineers who have learned from history, would point to the real-time clock chip that did hardware rules for things right for only one country for a mere three years in the 1980s, until the legislation changed, and whose behaviour has been wrong ever since. Step forward the MC146818, used in the PC/AT and emulated by chipsets since, whose built-in daylight savings time change rule implemented in hardware was rendered obsolete in 1987. http://catless.ncl.ac.uk./Risks/24.60.html#subj12.1 http://catless.ncl.ac.uk./Risks/24.60.html#subj12.1
- Gibbon1 3y agoOld electrical engineer I worked under in the 1980's mentioned he designed a clock calendar STD Bus card. Next design he replaced the whole thing with a 32 bit counter on the processor card and 250 bytes of Z80 assembly. Unrelated I think the lobbyists that got daylight savings time changed charged the BBQ manufacturers $50k.
