Date
Returns a formatted date/time string of type Long derived from seconds since
1990.
Syntax
Date(SecsSince1990, Option)
DaylightSaving
Defines daylight saving time. Determines if daylight saving time has begun or
ended. Optionally advances or turns‐back the datalogger clock one hour.
Syntax
variable = DaylightSaving(DSTSet, DSTnStart, DSTDayStart,
DSTMonthStart, DSTnEnd, DSTDayEnd, DSTMonthEnd, DSTHour)
DaylightSavingUS
Determine if US daylight saving time has begun or ended. Optionally advance or
turn‐back the datalogger clock one hour.
Syntax
variable = DaylightSavingUS(DSTSet)
IfTime
Returns a number indicating True (‐1) or False (0) based on the datalogger's realtime
clock.
Syntax
If (IfTime(TintoInt, Interval, Units)) Then
-or-
Variable = IfTime(TintoInt, Interval, Units)
PakBusClock
Sets the datalogger clock to the clock of the specified PakBus device.
Syntax
PakBusClock(PakBusAddr)
RealTime
Parses year, month, day, hour, minute, second, micro‐second, day of week,
and/or day of year from the datalogger clock.
Syntax
RealTime(Dest)
SecsSince1990
Returns seconds elapsed since 1990. DataType is LONG. Used with GetRecord().
Syntax
SecsSince1990(date, option)
TimeIntoInterval
Returns a number indicating True (‐1) or False (0) based on the datalogger's realtime
clock.
Syntax
Variable = TimeIntoInterval(TintoInt, Interval, Units)
-or-
If TimeIntoInterval(TintoInt, Interval, Units)
