Your statement is not entirely true. The Real-time search is the only portion that streams live/continous view of events, which I dont think you are using. When you run a search that does not include real-time you are just running report. Splunk will extracted _time from your log/event at time of index based on your props.conf. If you want Splunk to use the RECORD_DATE for your events timestamp you need to configure you props.conf for that source/sourcetype on your indexers.
#props.conf stanza example (only an example)
[RECORD]
NO_BINARY_CHECK=1
SHOULD_LINEMERGE=false
MAX_TIMESTAMP_LOOKAHEAD=38
TIME_PREFIX=RECORD_DATE=
TIME_FORMAT="%Y%m%d%H%M"
