Consider the following date string
2012-10-01 01:02:03.004+0500
This is recognized in Java using the following SimpleDateFormat pattern:
yyyy-MM-dd HH:mm:ss.SSSZ
If, however, the timezone information above is truncated to 2 digits, i.e. like
2012-10-01 01:02:03.004+05
the date string does not comply to any valid format, so there is no SimpleDateFormat pattern that could be used in order to correctly parse it.
Is there any workaround for parsing the truncated timezone correctly without string preprocessing?
If not, which regular expression would be optimal for that preprocessing to be done for a large number of such date strings in 1 round, e.g. using a replaceFirst() call, as in this similar question?
