How can I increment a custom field based on days elapsed since created date?

[Drew Nedderman]

I have this script to calculate a custom field. I want to increment 'customfield_12331' by 1 as every 7 days go by. Is this possible?

def input1CfId = 'customfield_12326' def input2CfId = 'customfield_12327' def input3CfId = 'customfield_12328' def input4CfId = 'customfield_12329' def input5CfId = 'customfield_12331' def outputCfId = 'customfield_12330' def projectKey = "MS" if (issue == null || issue.fields.project.key != projectKey) { logger.info("Wrong Project ${issue.fields.project.key}") return } def input1 = issue.fields[input1CfId] as Integer def input2 = issue.fields[input2CfId] as Integer def input3 = issue.fields[input3CfId] as Integer def input4 = issue.fields[input4CfId] as Integer def input4 = issue.fields[input5CfId] as Integer if (input1 == null || input2 == null || input3 == null || input4 == null) { logger.info("Calculation using ${input1}, ${input2}, ${input3}, and ${input4} was not possible") return } def output = input1 + input2 + input3 + (input4/2) + input5 if (output == (issue.fields[outputCfId] as Integer)) { logger.info("already been updated") return } put("/rest/api/2/issue/${issue.key}") //.queryString("overrideScreenSecurity", Boolean.TRUE) .header("Content-Type", "application/json") .body([ fields:[ (outputCfId): output ] ]) .asString()

Thank you
