I'm looking to add 1 second to a datetime so I can test date based pagination. I'm hoping get a date from our API response, convert the date string into a date, then convert that into milliseconds, add a second and then convert back into a datestring and use it in my next API request. ( sound longwinded? It sure feels like it is!)
I'm having and issue when I try to parse a dateTime. The following code is throwing an error:
def c= new date().parse("yyyy-mm-ddThh:mm:ss",lastDate)
log.info "new formatt"+lastDate
log.info c.timeInMillis
Error: groovy.lang.MissingMethodException: No signature of method: java.util.Date.parse() is applicable for argument types: (java.lang.String, groovy.util.slurpersupport.NodeChildren) values: [yyyy-mm-ddThh:mm:ss, 2007-01-26T00:00:00] Possible solutions: parse(java.lang.String), parse(java.lang.String, java.lang.String), wait(), clone(), any(), use(java.util.List, groovy.lang.Closure)
Any tips on how to achieve my goal? Or is it a dimwit approach?

Sounds like quite a round about way of adding a second. Why not just:
import groovy.time.TimeCategory
def lastDate = new Date()
use(TimeCategory) {
lastDate = lastDate + 1.second
}
For more flexible date string parsing, you might want to look at the JChronic java library. It can handle dates in many different formats and doesn't rely on having an exact template like the SimpleDateFormat class. Here's an example using both of these:
Date.metaClass.'static'.fromString = { str ->
com.mdimension.jchronic.Chronic.parse(str).beginCalendar.time
}
def lastDate = Date.fromString("2007-01-26T00:00:00")
use (TimeCategory) {
100.times {
runTest(lastDate)
lastDate = lastDate + 1.second
}
}
