Multiple variables in Jenkins shell - shell

Question

I try to print two variables in Jenkins shell (one of which is global one) . When I print them independently on shell for each it works, however when I try both variables on single line it fails. See the output, seems like a crop after the first variable .
I've tried to print two local variables, and it seems working. However I need the global one
#!/usr/bin/env groovy
def START
node ('master') {
// options{
// timestamps()
// }
stage("one") {
script{
START = sh(script: 'date --utc +%FT%T', returnStdout: true)
}
stage("two") {
def END = sh(script: 'date --utc +%FT%T', returnStdout: true)
sh "echo start $START"
sh "echo end $END"
sh "echo $START and $END"
}
}
}
+ date --utc +%FT%T
[Pipeline] sh
+ echo start 2019-08-01T14:48:08
start 2019-08-01T14:48:08
[Pipeline] sh
+ echo end 2019-08-01T14:48:09
end 2019-08-01T14:48:09
[Pipeline] sh
+ echo 2019-08-01T14:48:08
2019-08-01T14:48:08
+ and 2019-08-01T14:48:09

sh is a dedicated command of jenkins-groovy. The first two work because $START/$END are the final string and doesn't try to replace something else.
sh "echo ${START} and ${END}" writing the variables like this will limit the GString and convert only the correct part and wont try to convert the "and" also.
