Kdb+/q Developer – Level 2 - Casting - Casting Methods - Small error

In this lesson, there is a line that says:

`long$ts //number of miliseconds from midnight 1st Jan 2020

The comment should actually say:
//number of nanoseconds from midnight 1st Jan 2000

Also, the suggested short forms for minutes and seconds in an answer to a question does not work:

Hi @MW1
Thank you for flagging the date and time issue, I will have this corrected!
However, the short forms are returning correctly.

`uu$16:30:00

Returns the minutes value from the timestamp, hence why is returns 30i and:

`minute$16:30:00

Rounds the value to only include hours and minutes. For example if you had:

`minute$16:30:45 \\the output would be 16:30

I hope this clears things up!
