Appendix A. CRBasic Programming Instructions Trim Returns a copy of a string with no leading or trailing spaces. Syntax variable = Trim(TrimString) UpperCase Converts a string to all uppercase characters Syntax String = UpperCase(SourceString) A.8 Clock Functions Within the CR3000, time is stored as integer seconds and nanoseconds into the second since midnight, January 1, 1990. ClockChange Returns milliseconds of clock change due to any setting of the clock that occurred since the last execution of ClockChange. Syntax variable = ClockChange ClockReport Sends the datalogger clock value to a remote datalogger in the PakBus network. Syntax ClockReport(ComPort, RouterAddr, PakBusAddr) ClockSet Sets the datalogger clock from the values in an array. Syntax ClockSet(Source) 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) 508
