Struggling with Datetime Parsing - clickhouse

Question

Can I using some internal ch functions to convert this datetime format 5/11/2021 13:10:25 to YYYY-MM-DD hh:mm:ss ?
I'm quite struggling while find it out.
I've tried following:
replaceRegexpOne(toString(START_TIME), '\d{2}/\d{2}/\d{4}', '(\2)-(\1)-(\3)')
But got:
RROR: garbage after DateTime: "375291300"
ERROR: DateTime must be in YYYY-MM-DD hh:mm:ss or NNNNNNNNNN (unix timestamp, exactly 10 digits) format.
: (at row 1)
