You should be able to receive France's Allouis transmitter on 162KHz. It is a 2MW transmitter with a carrier accuracy of 2 parts in 10 to the 12th. I believe it carries a timecode.

I can't find any routine measurements of its accuracy, either. 198 KHz from Droitwich isn't receivable here, and may be off the air within a year or two if reports are to be believed:
