+.Dt ASN1_TIME_PARSE 3
+.Os
+.Sh NAME
+.Nm ASN1_time_parse,
+.Nm ASN1_time_tm_cmp
+.Nd LibreSSL utilities for asn1 format time.
+.Sh SYNOPSIS
+.In asn1.h
+.Ft "int"
+.Fn ASN1_time_parse "const char *bytes" "size_t len" "struct tm *tm" "int mode
+.Ft "int"
+.Fn ASN1_time_tm_cmp "struct tm *tm1" "struct tm *tm2" 
+.Sh DESCRIPTION
+The
+.Nm ASN1_time_parse
+function parses an asn1 time string of
+.Ar len
+bytes starting at
+.Ar bytes .
+The resulting time is stored in
+.Ar tm
+if 
+.Ar tm
+is non NULL. 
+.Pp
+The 
+.Ar mode
+parameter must be one of
+.Bl -bullet -offset four
+.It
+.Ar 0
+to parse a time as specified in RFC 5280 for an X509 object,
+which may be either a UTC time or a Generalized time. 
+.It
+.Ar V_ASN1_UTCTIME
+to parse an RFC 5280 format UTC time.
+.It
+.Ar V_ASN1_GENERALIZEDTIME 
+to parse an RFC 5280 format Generalized time.
+.El
+.Pp
+The
+.Nm ASN1_time_tm_cmp
+function compares two times in
+.Ar tm1
+and
+.Ar tm2
+.Sh RETURN VALUES
+.Nm ASN1_parse_time 
+returns
+.Bl -bullet -offset four
+.It
+.Ar -1
+if the string was invalid for the
+.Ar mode
+specified
+.It
+.Ar V_ASN1_UTCTIME 
+if the string parsed as a valid UTC time.
+.It :
+.Ar V_ASN1_GENERALIZEDTIME 
+if the string parsed as a valid Generalized time.
+.El
+.Pp
+.Nm ASN1_time_tm_cmp
+returns
+.Bl -bullet -offset four
+.It
+.Ar -1
+if tm1 is less than tm2.
+.It
+.Ar 1
+if tm1 is greater than tm2.
+.It
+.Ar 0
+if tm1 is the same as tm2.
