Time and date values
Time and date values are represented as a number of UTC seconds since 12:00 a.m. Jan. 1, 1970.
The
os.time()
command returns values in this format. Use
os.date()
to return values in month,
day, year, hours, and minutes format, or to access the timestamp table. The only exception to this is
the use of the
ptpseconds
recall attribute, which has the seconds in PTP format.
Time and date values are represented as the number of seconds since some base. Representing
time as a number of seconds is referred to as “standard time format.” The three time bases used for
the Series 3700A are:
•
UTC 12:00 am Jan 1, 1970.
Some examples of UTC time are reading buffer seconds, adjustment
dates, and the value returned by
os.time()
.
•
Instrument on.
References time to when the instrument was turned on. The value returned by
os.clock()
is referenced to the turn-on time.
•
Event.
Time referenced to an event, such as the first reading stored in a reading buffer.
