Customized rule is not working

Question

Hi All, 
 As part of the requirement, I have created a rule to convert text fields data into date and time. The rule is working fine on the UI, which executes one row at a time, but when the same rule is used in Process model using a!forEach for converting multiple text fields the data is not getting converted properly. 
 a!forEach( items: pv!subServiceOrder, /*this is the CDT*/ expression: { if(rule!SOA_checkIsBlank(fv!item.CreatedOn),{}, /*CreatedOn is the field on which time conversion has to happen, it is a text field */ rule!SOA_timeConversion( date:fv!item.CreatedOn, countryCode:fv!item.CountryCode , /* CountryCode is the field which contains the country code, based on which time conversion has to happen */ time:fv!item.TimeZone /* TimeZone is the field which contains the country code, on which time conversion to happen */ )) } ) 
 Attached SOA_timeConversion rule for reference

 local!counter: if(
 and(local!day>=10,local!month>=10),local!count+2,
 if(or(local!day>=10,local!month>=10),local!count+1,local!count)
 ),
 local!datasubset: a!queryEntity(
 entity: cons!SOA_ISO_COUNTRY_LIST,
 query: a!query(
 selection: a!querySelection(
 columns: 
 {
 a!queryColumn(
 field: "isoCountryTimeZone"
 ),
 a!queryColumn(
 field: "dayLightTimeDiff"
 ),
 a!queryColumn(
 field: "observeDST"
 )
 }
 ),
 filter: a!queryFilter(
 field: "isoCountryCode",
 operator: "in",
 value: ri!countryCode
 ),
 pagingInfo: a!pagingInfo(1,-1)
 )
 ).data,
 if(
 and(local!datasubset.observeDST = "1",isindaylightsavingtime(local!x,local!datasubset.isoCountryTimeZone)),
 left(tostring(local!x+(todecimal(ri!time)/24)+(todecimal(local!datasubset.dayLightTimeDiff)/24)),local!counter),
 left(tostring(local!x+(todecimal(ri!time)/24)),local!counter)
 /*substitute(tostring(local!x+timezone)," GMT+00:00","")*/
 ) 
)

Please let me know if there are any changes that are to be made for the rule. 
 Thanks in advance.
