How to remove milliseconds from LocalDateTime.now()

How to Exclude Milliseconds from LocalDateTime.now()

When processing dates and times with LocalDateTime.now() in the yyyy-MM-dd HH:mm:ss pattern, you might experience a slight discrepancy of one second, even if the times seem identical.

This discrepancy happens due to the rounding of 0.xxxx second milliseconds. Some people suggest using DateTimeFormatter to modify the format. However, this could be an inconvenient process for those who need LocalDateTime objects, not Strings, as it involves converting and reconverting.

Fortunately, there's a straightforward way to omit milliseconds right from the start, as demonstrated in the code snippet below:

LocalDateTime.now().withNano(0)

By applying the .withNano(0) function as shown above, you can generate a time without milliseconds.
