time.time() is off by 30 years

[dannybr]

after running ntp, the time.localtime() is fine, but time.time() is off by some 30 years!

time.time() returns the seconds since the EPOCH, which is the 1.1.2000 on an ESP32. That's returned by time.gmtime()[0]. Testing it on an ESP32, it returns something like 764_005_006, which is a reasonable number right. For getting a time since 1.1.1970, you have to add 946_684_800.

The majority of MCU ports of Micropython uses a different epoch (start datetime) than CPython.

epoch of 2000-01-01 00:00:00 UTC. Epoch year may be determined with gmtime(0)[0].

See https://docs.micropython.org/en/latest/library/time.html

RTFM, but then again it’s our 600 paged :-) IMHO, this should be in CPYthon Micropython difference section. thanks, danny

Just don't print it, use the micropython stubs instead
