time zone specifier

My understanding is that if I put GMT0BST,M3.5.0,M10.5.0 in the config file, I will get daylight saving times from time$ during summer time in the UK as specified (M3:March to M10:October). But it doesn't seem to work! Ideas?

Changing GMT0BST to GMT1BST seemed intuitive but didn't do anything.

The file https://github.com/nayarsystems/posix_t ... /zones.csv
reports GMT0BST,M3.5.0/1,M10.5.0 for London

Try it as this, Stuart.

GMT0BST,M3.5.0/1,M10.5.0

Silly me. Saving the config isn't enough, you have to power cycle the chip and restart it. It must only be looked at at power-up. As this particular one is built in to something it doesn't get power cycled normally. For anyone else's benefit, GMT0BST,M3.5.0/1,M10.5.0 does work for UK to get GMT in the winter and BST in the summer from the time$ function.

Thanks guys

You don't actually need to reboot the system, just force sync with the NTP server using OPTION.NTPSYNC in the "immediate" window of the editor.
