I have a data set with the date as shown in the sample data. I wish to separate the variable "date_GMT" into two variables of date and time. Time should be in 24-hour military time format in the Central European Time zone. How can I do this in Stata?. Many thanks for your time in advance.

date_unix date_GMT
