Identifying files with a timestamp greater than a given timestamp
I need to be able to identify files with file timestamps greater than a given timestamp.
I am using the following solution, although it appears to compare files at the "seconds" granularity and I need it at the milliseconds. When I tested my solution, it missed files that had timestamps greater than the given timestamp, but had the same "seconds" as the given timestamp.
Code:
#!/bin/ksh
DT_TMSTMP='2012-04-10 08:39:17.807192000'
touch --date "$DT_TMSTMP" ./last_date
for i in `find $INFA_SHARED/SrcFiles/NANTEST/Src -newer ./last_date`
do
print $i
done
exit

dcecp_utc
utc(1m)utc(1m)NAME
utc - A dcecp object that manipulates UTC timestamps
SYNOPSIS
utc add timestamp relative_timestamp
utc compare absolute_timestamp absolute_timestamp [-noinaccuracy]
utc convert absolute_timestamp [-gmt]
utc help [operation | -verbose]
utc multiply relative_timestamp {integer | floating_point_factor}
utc operations
utc subtract timestamp timestamp
ARGUMENTS
An International Organization for Standardization (ISO) compliant time format of the following form: CCYY-MMDD-
hh:mm:ss.fff[+|-]hh:mmIsss.fff The Time Differential Factor (TDF) component [+|-]hh.mm, if present, indicates the offset from Universal
Time Coordinated (UTC) time and implies local system time. The inaccuracy component Iss.fff, if present, specifies the duration of the
time interval that contains the absolute time. A floating-point number such as 53.234. A whole number such as 79. The name of the utc
operation for which to display help information. A Distributed Time Service (DTS) timestamp of the following form: [-]DD-hh:mm:ss.fff-
Iss.fff Relative times often omit fractions of seconds (the leftmost .fff sequence) and generally lack an inaccuracy component (Iss.fff).
For example, a relative time of 21 days, 8 hours, and 15 minutes is expressed as 21-08:15:00. A utc timestamp that can be a relative or
absolute time. See the relative_timestamp and absolute_timestamp argument descriptions for the format of these timestamps.
DESCRIPTION
The utc object lets you add, compare, and convert timestamps in DTS and ISO formats.
OPERATIONS
utc add
Adds two timestamps. The syntax is as follows: utc add timestamp relative_timestamp
The add operation returns the sum of two timestamps. The timestamps can be two relative times or an absolute time and a relative time.
Privileges Required
No special privileges are needed to use the utc add command.
Examples
dcecp> utc add 1994-10-18-13:21:50.419-04:00I----- +0-00:02:00.000I----- 1994-10-18-13:23:50.419-04:00I----- dcecp>
utc compare
Compares two absolute timestamps indicating the temporal order. The syntax is as follows: utc compare absolute_timestamp absolute_time-
stamp [-noinaccuracy]
The compare operation compares two timestamps and returns -1 if the first is earlier, 1 if the second is earlier, and 0 if the difference
is indeterminate. Specify the -noinaccuracy option to ignore inaccuracies in comparisons; in this case a return of 0 indicates the times
are the same.
Privileges Required
No special privileges are needed to use the utc compare command.
Examples
dcecp> utc compare 1994-10-18-13:22:32.816-04:00I----- > 1994-10-18-13:21:50.419-04:00I----- -noinaccuracy 1 dcecp>
utc convert
Converts a timestamp from UTC to local time. The syntax is as follows: utc convert absolute_timestamp [-gmt]
The convert operation accepts a timestamp and returns another timestamp that expresses the same time in the local time zone. If called
with the -gmt option it returns a Greenwich mean time (GMT) formatted timestamp.
Privileges Required
No special privileges are needed to use the utc convert command.
Examples
dcecp> utc convert 1994-10-18-13:22:32.816-00:00I----- 1994-10-18-09:22:32.816-04:00I----- dcecp>
dcecp> utc convert 1994-10-18-13:22:32.816-00:00I----- -gmt 1994-10-18-13:22:32.816I----- dcecp>
utc help
Returns help information about the utc object and its operations. The syntax is as follows: utc help [operation | -verbose]
Options Displays information about the utc object.
Used without an argument or option, the utc help command returns brief information about each utc operation. The optional operation argu-
ment is the name of an operation about which you want detailed information. Alternatively, you can use the -verbose option for more
detailed information about the utc object itself.
Privileges Required
No special privileges are needed to use the utc help command.
Examples
dcecp> utc help add Adds a relative and absolute, or two relative, timestamps. compare Compares two timestamps
to determine which is earlier. convert Converts a timestamp into the local timezone or GMT. multiply Multiplies a
relative timestamp by a number. subtract Returns the difference between two timestamps. help Prints a summary
of command-line options. operations Returns a list of the valid operations for this command. dcecp>
utc multiply
Multiplies a relative time (a length of time) by an integer or floating-point factor. The syntax is as follows: utc multiply rela-
tive_timestamp {integer | floating_point_factor}
The multiply operation accepts two arguments: a relative timestamp and an integer or floating-point factor. It multiplies the length of
time (specified by the relative timestamp) by the integer or floating-point factor, returning the product as a relative timestamp.
Privileges Required
No special privileges are needed to use the utc multiply command.
Examples
dcecp> utc multiply +0-00:00:05.000I----- 3 +0-00:00:15.000I----- dcecp>
utc operations
Returns a list of the operations supported by the utc object. The syntax is as follows: utc operations
The list of available operations is in alphabetical order except for help and operations, which are listed last.
Privileges Required
No special privileges are needed to use the utc operations command.
Examples
dcecp> utc operations add compare convert multiply subtract help operations dcecp>
utc subtract
Subtracts one timestamp from another, returning the difference as a relative timestamp. The syntax is as follows: utc subtract timestamp
timestamp
The subtract operation returns the difference between two timestamps that express either an absolute time and a relative time, two relative
times, or two absolute times. Subtracting an absolute timestamp from a relative timestamp, however, is not allowed. The return value is
an absolute or relative timestamp, depending on how the command is used.
Privileges Required
No special privileges are needed to use the utc subtract command.
Examples
dcecp> utc subtract 1994-10-18-13:22:32.816-00:00I----- +0-00:00:15.000I----- 1994-10-18-13:22:17.816+00:00I----- dcecp>
