A pasted drop list whose line breaks had become spaces was stored as one pattern that matched nothing, so Home Assistant's two 526-series bookkeeping families filled the 1,000-series cap. No metric name holds whitespace, so patterns now split on spaces and tabs as well as lines and commas. Home Assistant names its Unix times *_time_seconds (e.g. homeassistant_last_updated_time_seconds), which read as "20751d 21h". is_moment() takes both suffixes, for the value shown and the chart axis.
