add*

This function is used by Ignition's Expression language.

Description

This function is a set of functions that include:

FunctionDescription
addMillisAdd or subtract an amount of milliseconds to a given date and time.
addSecondsAdd or subtract an amount of seconds to a given date and time.
addMinutesAdd or subtract an amount of minutes to a given date and time.
addHoursAdd or subtract an amount of hours to a given date and time.
addDaysAdd or subtract an amount of days to a given date and time.
addWeeksAdd or subtract an amount of weeks to a given date and time.
addMonthsAdd or subtract an amount of months to a given date and time. This function is unique since each month can have a variable number of days. For example, if the date passed in is March 31st, and we add one month, April does not have a 31st day, so the returned date will be the proper number of months rounded down to the closest available day, in this case April 30th.
addYearsAdd or subtract an amount of years to a given date and time.
