- All Implemented Interfaces:
-
io.anyline.nfc.bouncycastle.asn1.ASN1Encodable
,io.anyline.nfc.bouncycastle.util.Encodable
public class ASN1UTCTime extends ASN1Primitive
- * UTC time object. Internal facade of ASN1UTCTime.
This datatype is valid only from 1950-01-01 00:00:00 UTC until 2049-12-31 23:59:59 UTC.

11.8 UTCTime
11.8.1 The encoding shall terminate with "Z", as described in the ITU-T X.680 | ISO/IEC 8824-1 clause on UTCTime.11.8.2 The seconds element shall always be present.
11.8.3 Midnight (GMT) shall be represented in the form:
"YYMMDD000000Z" where "YYMMDD" represents the day following the midnight in question.

Constructor Summary
Constructors Constructor Description ASN1UTCTime(String time)
The correct format for this is YYMMDDHHMMSSZ (it used to be that seconds were never encoded. ASN1UTCTime(Date time)
Base constructor from a java.util. ASN1UTCTime(Date time, Locale locale)
Base constructor from a java.util.date and Locale - you may need to use this if the default locale doesn't use a Gregorian calender so that the GeneralizedTime produced is compatible with other ASN.1 implementations.

ASN1UTCTime
ASN1UTCTime(String time)
The correct format for this is YYMMDDHHMMSSZ (it used to be that seconds were never encoded.- Parameters:
time
- the time string.
-
ASN1UTCTime
ASN1UTCTime(Date time)
Base constructor from a java.util.- Parameters:
time
- the Date to build the time from.
-
ASN1UTCTime
ASN1UTCTime(Date time, Locale locale)
Base constructor from a java.util.date and Locale - you may need to use this if the default locale doesn't use a Gregorian calender so that the GeneralizedTime produced is compatible with other ASN.1 implementations.- Parameters:
time
- a date object representing the time of interest.locale
- an appropriate Locale for producing an ASN.1 UTCTime value.
-

Method Detail
-
getInstance
static ASN1UTCTime getInstance(Object obj)
Return an UTC Time from the passed in object.
- Parameters:
obj
- an ASN1UTCTime or an object that can be converted into one.- Returns:
an ASN1UTCTime instance, or null.
-
getInstance
static ASN1UTCTime getInstance(ASN1TaggedObject taggedObject, boolean explicit)
Return an UTC Time from a tagged object.
- Parameters:
taggedObject
- the tagged object holding the object we wantexplicit
- true if the object is meant to be explicitly tagged false otherwise.- Returns:
an ASN1UTCTime instance, or null.
-
getDate
Date getDate()
Return the time as a date based on whatever a 2 digit year will return. For standardised processing use getAdjustedDate().
- Returns:
the resulting date
-
getAdjustedDate
Date getAdjustedDate()
Return the time as an adjusted date in the range of 1950 - 2049.
- Returns:
a date in the range of 1950 to 2049.
-
getTime
String getTime()
Return the time - always in the form of YYMMDDhhmmssGMT(+hh:mm|-hh:mm).
Normally in a certificate we would expect "Z" rather than "GMT", however adding the "GMT" means we can just use:
To read in the time and get a date which is compatible with our local time zone.dateF = new SimpleDateFormat("yyMMddHHmmssz");
Note: In some cases, due to the local date processing, this may lead to unexpected results. If you want to stick the normal convention of 1950 to 2049 use the getAdjustedTime() method.
-
getAdjustedTime
String getAdjustedTime()
Return a time string as an adjusted date with a 4 digit year. This goes in the range of 1950 - 2049.
