it does need a different design, but a buried oscillator, 5 to 8 meter
deep in the garden has the best temperature stabilization, just don't
turn thee power off, but that could be done using the old Greek
water-clock principle, the spill over stabilizer. In the Bay Area
[California] the soil's temperature is around the year approximately
17C° ±0.01C° if you go further down it will be even more constant,
without any heating power and control loop....

Hi
A lot depends on the oscillator. My fine old GR rack mount took most of 9
months to settle most of the way. It was still dropping in a year after that
when I stopped watching it. Some of my T-Bolts took a week, some took a couple
months….
Best thing you can do with any OCXO is just leave it on power.

An oscillator can take many weeks to settle in after being powered off /
shipped / abused / looked at cross-eyed / etc. It typically takes a
Thunderbolt a month or two to settle down after being shipped from China.
