Remarks

When to use STOT( )

Use the STOT( ) function to convert serial times to regular times.

What are serial times?

Analytics serial times represent a fractional portion of 24 hours, with 24 hours equaling 1.

For example:

the serial time equivalent of 1 hour is 1/24, or 0.04167
the serial time equivalent of 1 minute is 1/1440, or 0.0006945

Serial times can be prefaced with a '0' (zero) and a decimal point, or just a decimal point.

1.000000 is not a valid serial time

Although 24 hours equals 1 for the purposes of calculating serial times, 1.000000 is not a valid serial time. Valid serial times are all decimal fractions less than 1. For example: 0.75000 (06:00:00 PM).

Analytics treats the serial number 1.000000 as the serial datetime equivalent to 02 Jan 1900 12:00:00 AM. Because STOT( ) ignores the date portion of datetimes, STOT(1.000000) is equivalent to STOT(0.000000) and both are equivalent to the regular time 12:00:00 AM.
