UPDATED

• Modified the decode_cf_datetime function in xarray/coding/times.py to include the variable name in the error message. The function now captures the specific variable name causing the error and adds it to the error message to assist users in diagnosing issues more effectively.

CHANGED

• Updated various functions that call decode_cf_datetime to pass the accurate variable name parameter. Functions such as CFDatetimeCoder in xarray/conventions.py have been modified to include the name argument, ensuring that the variable name is now passed along when decoding time units, improving error messaging and clarity for users.
