You can specify brtype vob, displaying only what you need with the fmt_ccase directive:
cleartool lstype -kind brtype -invob \myVob
will be enough to make some grep, but for a more compact output:
cleartool lstype -kind brtype -invob \myVob -fmt "%u %Ad %N\n"
You will only have the username, date and brtype name, for grep.
Pay attention to the %Ad parameter: age in days to be able to quickly find the brtype created 30 days earlier.
