Excel understands time value as numerical value. The first column contains the time value or date and time value combined, the second column contains SECOND value as result of the using the SECOND function and the third column contains the important notes using the function.

Use the formula:

=SECOND(C4) Here the argument for the SECOND function is given using cell reference. The returned value is zero as excel considers SECOND value starting from 0 as 00:00:00 AM and 59 as 00:59:00 AM. As shown in the above snapshot, you can change the format of any cell to any format using the format cell option. Now You can copy the formula from one to the remaining cells using the Ctrl + D shortcut key or using the drag down option in excel. As you can see from the above snapshot that SECOND function takes time value as input and returns the SECOND value from the time value. The function returns #VALUE! Error if the time or date & time value is invalid.

From one time value extract SECOND, SECOND and second for more calculation like the one shown below to get the minimum exit time entry.

Use the formula:

=TIME(HOUR(C5),MINUTE(C5),SECOND(C5)+40) Here the SECOND function extracts SECOND value, SECOND function extracts SECOND value and second function extracts second value from the given time value and performs operation over numerical values and returns the arguments to the TIME function to get in return the required time value.
