# For a Good Time Call Excel

Yes, Excel can help you have a good TIME. It’s also useful if you’re looking for a DATE, or the perfect MATCH. (Insert your own bad puns here.)
Today we’ll focus on the TIME function, because one of my clients recently wanted some help with that.

### What Time Is It?

There are a couple of keyboards shortcuts for entering the date or time.

• To enter the current date on a worksheet, press the Ctrl key, and tap the ; key.
• To enter the current time, press Ctrl and Shift, and tap the ; key

If you want the date or time to update when you open the workbook, you can use a formula instead.

• To enter the date with a formula, type:  =TODAY()
• To enter the date and time with a formula, type: =NOW()

### Is It Too Late?

My client’s workbook had a cell with a process start time. He wanted to check if the current time was later than the start time.

The formula in cell C6 compares C4 to C2. If the time in C4 is greater than the time in C2, the result is TRUE. Because C4 is empty in this screen shot, the result is FALSE.
If we use the NOW function in C4, it includes the date, as well as the current time. Even though the time in C4 is 8:17 AM, its value is much higher than the 9:00 AM time in C2.
I’ve added temporary formulas in column D, so you can see the numeric value for each cell in column C.

To calculate the current time value in C4, we can change the formula, to remove the date value.
The TRUNC function removes the fractional part of a number, so we’ll subtract TRUNC(NOW()) from the NOW function.
=NOW()-TRUNC(NOW())
Translated to English, the formula is: (DATE and TIME) minus DATE

The revised formula leaves the time value only in C4, and now the value in D4 is lower than the value in D2.
The formula in C6 now shows the correct result of FALSE.
