The times are getting changed when stored to MS SQL.
I’m reading a time stamp out of a Siemens PLC (array of bytes). And converting it with datetime.datetime
import datetime
logger = system.util.getLogger("MyLogger")
logger.warn('SiemensDate Hour:' + str(h))
return datetime.datetime(y,m,d,h,i,s,0)
---Logger reported: SiemensDate Hour:16
and this bit of code in the calling subroutine printed this:
MyFunc.MsgBox('GateWay/TagChange/GetBatchData/Script: MyTime =
MyFunc.SiemensDate ' + str(MyTime)
---Logger reported: 2021-10-25 16:52:51
Point being, I’m getting the time correct from the PLC. However, when running the Named Query they are getting changed.
params = {'id':BTblID,
'Start_inHg': MyData['VacuumCheckStart(inHg)'],
'Stop_inHg': MyData['VacuumCheckStop(inHg)'],
'StartTStamp': MyFunc.SiemensDate(MyData['BatchStart(Time)']),
'CoolTStamp' : MyFunc.SiemensDate(MyData['CoolStart(Time)']),
'StopTStamp': MyFunc.SiemensDate(MyData['BatchStop(Time)']),
'Start_inHgTStamp':MyFunc.SiemensDate(MyData['VacuumCheckStart(Time)']),
'Stop_inHgTStamp': MyFunc.SiemensDate(MyData['VacuumCheckStop(Time)']),
'HeatSetStartTStamp': MyFunc.SiemensDate(MyData['HeatSetStart(Time)'])}
BTbl = system.db.runNamedQuery('AN75/UpdateBatchTbl',params)
MyFunc.MsgBox('GateWay/TagChange/GetBatchData/Script:' + str(params))
---Logger reported: GateWay/TagChange/GetBatchData/Script:{'StartTStamp':
datetime.datetime(2021,10, 25, 16, 52, 51), 'Start_inHgTStamp': datetime.
datetime(2021, 10, 25, 16, 51, 21), 'Start_inHg': -29.20303, 'Stop_inHgTStamp':
datetime.datetime(2021, 10, 25, 16, 52, 21), 'HeatSetStartTStamp': datetime.
datetime(2021, 10, 25, 16, 53, 47), 'Stop_inHg': -29.179539, 'id': 31, 'StopTStamp':

The Named Query in question:
This is a Trace from SQL Server Profiler. But what is being sent to SQL is using datetime2 declaration, and has been converted to UTC. Can I turn this off? Or do I need to convert times to local time w/every select statement? - is there a function for that?
