today.com is a bit flaky #17

Closed jayacotton closed 3 years ago

It looks like today.com will not always compute the correct time of day. After about 9PM it gets the hour off by 1. This may be due to time zone computation.

its worse that I thought. K>date Mon Mar 29 12:54:15 2021

K>today Today is Wednesday, the thirteenth day of October, two thousand and sixty-six. In thirty-seven seconds, the time will be twenty-one minutes before six PM, Daylight Savings Time. The moon is in its last quarter.

well, it seems to be working now. I will check it a few more times and then close this bug. C>today Today is Monday, the twenty-ninth day of March, two thousand and twenty-one. The time is twenty-six minutes and thirty seconds after nine PM, Daylight Savings Time. The moon is full.

C>date Mon Mar 29 21:26:44 2021

And for the curious. Date uses the RTC chip to get the date, as set by ntp. Ntp also sets the Epoch. From there Today calculates the time by working with Epoch and time from last ntp.

This seems to have gone away on its own. I suspect a mismatch in struct fram (i.e. old code)
