This is quite easy to add.I've never used an RTC but it does interest me as I would love to have the data and time included as that would save me a lot of hassle post processing the data...
Has said above depends on current draw , Save power by sleep and turn off epprom/sd card when not needed)So it needs to work off a 9v battery, so perhaps I might be forced into hourly recordings less accurate but better than daily max/min values from there weather station that might hopefully still be manned...
The SD caard requires 4 pins to communicate with it, Not sure how you would do it in C, I use PDS(Proton Development sutie)If I went the SD route, how would I connect it in hardware and communicate with it in software?
I would say EEprom now you said about the conditions it will be in.What is the best method?
I wold be he same, If your area is correct in the PDF file I know it well worked there enough timesYou also have me curious as to where you live? as i'm not from Wolverhampton but close enough to study there...

You don't specify the number of bytes per sample. Would 128K bytes be enough?
Serial MRAM, 128Kx8, SPI bus:
**broken link removed**
Benefits of MRAM:
- No battery backup required.
- Writes extremely fast compared to FLASH and EEPROM.
- Unlimited write. Don't have to worry about writing too many times to a memory byte of sector like other technologies.
