My 7:30pm scene just triggered at approx 4pm today! Checking the date/time showed Vera lite (1.5.346) had reverted back to 22nd December. I have London time zone.
I tried changing the time zone to something different. Rebooted. Changed back to London. Rebooted. Still date/time is very wrong.
In the end I followed Futzle’s instructions from an old thread to SSH and install ntpclient. This worked for me.

I’m posting this in case anyone else experiences the same issue today (if this is Vera bug). Could be related to a new router I installed a few days ago. ISP is Virgin Media in UK.
