A time value in one of the following formats:"h:m:s am/pm", "h:m:s", "h:m"
Converts a time value to seconds.
Converts a Formatted_Time containing a time value to an integer Count equal to the number of seconds past midnight. You typically use TOSECONDS() to perform time arithmetic to compute the elapsed time between a starting and ending time, or to compute an ending time from a start time and an elapsed time. The TOSECONDS() function supports fractional seconds, e.g. toseconds("3:23:05.23 pm").
toseconds("23") -> 23 toseconds("12:23") -> 44,580 toseconds("2:3:15") -> 7,395 toseconds("2:3:15 PM") -> 50,595
Assume you stored the time at which an event started in a field called START, and the time at which the event ended in a field called end. To compute the duration of the event, you use the following expression:
toseconds(end) - toseconds(START)
