clock format from ISO8601 to numerical
Hello, I have variable with a timestamp like this "2017-04-26T15:09:49.228Z" and I need to convert to numerical (just seconds). I try [clock format $nbf -format {%s}] I get a TCL error "- expected integer but got "2017-04-26T15:09:49.228Z" while executing "clock format $nbf -format {%s}"" Have anyone a idea how I can solve this format problem?
