Techniques perform log management. Such techniques involve obtaining a count value of a counter associated with a log entry in the log, the count value of the counter incrementing at a predetermined frequency. Such techniques further involve determining a rough time instant when the log entry is created based on the count value, a reference count value of the counter associated with the log entry, a reference time corresponding to the reference count value and the frequency. Such techniques further involve correcting the rough time instant based at least in part on the frequency and a set of count values of the counter corresponding to a set of time instants, to determine a corrected time when the log entry is created. Accordingly, the log backed up to the external storage device has accurate time information.
