Question

How can I write a regex for MM:DD:YYYY:HH:MM:SS?

Answer 1

It depends whether you want to check are all characters divided by : numbers or you also want to check whether you will not get totaly improper data like the 32nd of December or the hour like 25:66. To have such a basic validation you should use a little more complex regexp than the one provided by @Pascal MARTIN, e.g.,

[0-1][0-9]:[0-3][0-9]:[1-2][0-9]{3}:[0-2][0-9]:[0-5][0-9]:[0-5][0-9]
