Don't worry, it's very old 'legacy' stuff, meaning actual DRAM refresh is done thru totally different channels, you can use the PIT channel as suggested by Japheth without any fear.

Another - easy - suggestion for your original timing question, since you don't need high precision, you may check the seconds count in "CMOS" SRAM registers.
