Default The time was 1,666,666,666

Taking the Linux epoch and adding 1,666,666,666 seconds gives 2022-10-25 02:57:46+00:00
At time of posting that was about 9 1/2 hours ago.

The previous interesting time was 666,666,666 seconds. 1991-02-16 01:11:06+00:00

The next interesting time will be 6,666,666,666 seconds. 2181-04-04 11:51:06+00:00

Or, if you are not sure if you can make till then, try for 2,666,666,666 seconds. 2054-07-03 04:44:26+00:00

The future times given are merely aspirational. Leap seconds, both plus or minus, won't alter the given values because UTC is stupid. For those using TAI or similar you are on your own to figure it out. Good luck predicting the leap seconds 158 years into the future.

I suggest the next interesting time will s2G --- when signed 32-bit time-t variables go negative.

Cool, I missed 1901 the first time. Might have a shot at the second go-round.
https://en.wikipedia.org/wiki/Year_2038_problem
As usual, VMS shone here too. "While the native APIs of OpenVMS can support timestamps up to the 31st of July 31086, the C runtime library (CRTL) uses 32-bit integers for time_t. As part of Y2K compliance work that was carried out in 1998, the CRTL was modified to use unsigned 32-bit integers to represent time; extending the range of time_t up to 7 February 2106."
Windows' 64-bit counter of 100ns ticks from 1600-01-01 provides a range of ~58,494.2417 years if unsigned.

It would be good to be current on NTP server version. https://www.kb.cert.org/vuls/id/584606/

Where I used to work, we had an expensive DEC Printserver20 letter/ledger duplexing network printer shared by VMS Vaxes to a PC network, that quit working in September 1999. (99/09/09 I think.) By then the Vaxes were being replaced by Windows NT PCs and we were wrapping up Y2K readiness there, and the printer was several years old and outclassed by what was available new at less cost, so we sold it off and replaced it. The actual Y2K rollover was a nonevent for us, anticlimactic. So much so that the boss thought for a while that meant we could ignore IPV6 readiness to the last moment.

I remember seeing a clock in New Zealand display the year as 19100.

Someone had used string concatenation instead of arithmetic addition.

All power went out in MSFT's UK headquarters on the dot of 12:00 on the 99th day of 1999.

Remarkably little failed, mostly because everyone had been paying attention for years before but that didn't stop me being on call-out alert for the period around 2000.000

Yeah... Few appreciate how much work goes into ensuring stuff doesn't fail... 24/7/~52...

Our small team of ~50 people was in our office, monitoring stuff...

We weren't running any Cobol, so /most/ everything was fine...

The young just have no idea...

Isn't 1,000,000,000 seconds interesting?

Sure, if you like.

1B is 2001-09-09 01:46:40+00:00
2B is 2033-05-18 03:33:20+00:00
3B is 2065-01-24 05:20:00+00:00
10B is 2286-11-20 17:46:40+00:00
100B is 5138-11-16 09:46:40+00:00
1T is 33658-09-27 01:46:40+00:00

Perhaps your greatn-grandchildren will celebrate 1T seconds with a big solar system spanning party.

I /think/ I understand your humor. I hope you et al understand my seriousness.

I'm currently working in a space that requires sampling at 10 kHz. Multiple channels. Clever code; dedicated co-processor.

Jolly good fun. And, very efficient.

I trust that makes sense...
