Tech Tip: Timekeeping Analysis

A common question of late has had to do with calculating time passed, example – hours and minutes worked. There are two built in IDEA functions – rarely used, often forgotten.

@Tton – Converts a Time field that has values stored in Time format (HH:MM:SS) to a Numeric field with the time value converted into seconds. This is the reverse of @Ntot.

@Ntot – Converts a Numeric field containing time stored as seconds to a Time field type with a Time format (HH:MM:SS).
