How to edit my sourcetype in props.conf to prevent Splunk from splitting events at every timestamp?

I've got my props.conf set up for reading entire files as one event as such: [sourcetypename] SHOULD_LINEMERGE = false LINE_BREAKER = ((*FAIL)) TRUNCATE = 999999999 MAX_EVENTS = 999999999 The file I am reading has multiple timestamps in it, and Splunk will split it into multiple events at every timestamp. How can I prevent the events from splitting at every timestamp?
