I am new to shell scripting. The heart of my script is to find the difference between two timestamps up to milliseconds. With me I have a file with content of timestamps only as
2012-09-13 15:00:29,290 2012-09-13 15:00:29,297 2012-09-13 15:00:29,428 2012-09-13 15:00:29,447
Like this I have around 30k records, where I should not face any performance issue when I execute script. Many factors like leap year, months with 31 days etc come into picture when I am trying to write script for this.
Can anyone help me on this please?
