the only caller (date_time) for this sends num = NULL, so this
triggers a segfault.

the only reference I could find to that apparently unused parameter comes from:
93cfa7c7a8 ("approxidate_careful() reports errorneous date string", 2010-01-26)
and seems to indicate it is optional and therefore a check for NULL
might make sense for all other cases
